急，安装jabber服务器时，出现如下问题，在线等

sumargin

./configure --enable-ssl --enable-mysql --enable-idn \
      --with-extra-include-path=/usr/include/mysql \
      --with-extra-library-path=/usr/lib/mysql \
      --prefix=/opt/jabberd2

出现如下问题
configure: error: OpenSSL >= 0.9.6b not found

但我apt-get install openssl 显示已经安装

不知如何解决
不知openssl安装后是哪个类库，叫什么名字？
--with-extra-library-path=/lib也不行

./configure --help内容 如下：
`configure' configures jabberd 2.0s11 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR           user executables [EPREFIX/bin]
  --sbindir=DIR          system admin executables [EPREFIX/sbin]
  --libexecdir=DIR       program executables [EPREFIX/libexec]
  --datadir=DIR          read-only architecture-independent data [PREFIX/share]
  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
  --libdir=DIR           object code libraries [EPREFIX/lib]
  --includedir=DIR       C header files [PREFIX/include]
  --oldincludedir=DIR    C header files for non-gcc [/usr/include]
  --infodir=DIR          info documentation [PREFIX/info]
  --mandir=DIR           man documentation [PREFIX/man]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

Optional Features:
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-developer      Compile with warnings and debugging symbols
  --disable-dependency-tracking  speeds up one-time build
  --enable-dependency-tracking   do not reject slow dependency extractors
  --enable-static[=PKGS]
                          build static libraries [default=no]
  --enable-shared[=PKGS]
                          build shared libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-idn            enable IDN support (yes)
  --enable-ssl            enable SSL/TLS support (yes)
  --enable-mysql          enable MySQL auth/reg/storage support (yes)
  --enable-pgsql          enable PostgreSQL auth/reg/storage support (no)
  --enable-sqlite         enable SQLite 3 storage support (no)
  --enable-db             enable Berkeley DB auth/reg/storage support (no)
  --enable-ldap           enable OpenLDAP auth/reg support (no)
  --enable-pam            enable PAM auth/reg support (no)
  --enable-pipe           enable pipe auth/reg support (no)
  --enable-anon           enable anonymous auth/reg support (no)
  --enable-fs             enable filesystem storage support (no)
  --enable-oracle         enable Oracle auth/reg/storage support (no)
  --enable-mio=BACKEND    use BACKEND to drive MIO
  --enable-debug          enable debug messages
  --enable-nad-debug      enable NAD pointer tracking
  --enable-pool-debug     enable memory pool statistics

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-pic              try to use only PIC/non-PIC objects [default=use

  --with-extra-library-path
                          use additional library paths
--with-oracle-home=DIR   the Oracle home directory, for includes and libs.

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
              headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  CXXCPP      C++ preprocessor
  F77         Fortran 77 compiler command
  FFLAGS      Fortran 77 compiler flags

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
