编译软件总是出错

qeming

系统是2005.1-r1 升级了GCC到3.3.6，装了xorg7.0，gnome 2.14，编译软件时出错提示如下：

Call stack:
  ebuild.sh, line 1526:   Called dyn_compile
  ebuild.sh, line 923:   Called src_compile
  cairo-1.0.2.ebuild, line 54:   Called die

!!! Compilation failed
!!! If you need support, post the topmost build error, and the call stack if relevant.

我以为是portage 的问题，升级portage 到 2.1_pre7 问题依旧。问题是在编译 gnome 过程中出现的，因编译不过 epiphany 。提示错误好像是出在 libxml2 上，因此我重新编译了一遍libxml2。结果就出现这样的问题了，编译好几个软件都出现这样的问题，上面是编译 cairo 时的出错提示
