整合apache和weblogic过程中遇到下面的问题!!

aashen

# ./httpd -t
Syntax error on line 1039 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache2/modules/mod_wl_20.so into server: ld.so.1: ./httpd: fatal: relocation error: file /usr/local/apache2/modules/mod_wl_20.so: symbol apr_pool_create: referenced symbol not found
#


为什么会报这个错误呢？
