在生产中（在 AIX 5.3 上）的 modperl 设置下使用 XML::Parser 时遇到了问题。它在开发中工作正常，但在生产中失败并出现以下错误：

expat/expat-devel 库是/opt/freeware/lib使用一个包安装的（在开发和实时版本中相同），并且两者都显示相同的输出ldd Expat.so：

Expat.so needs:
     /usr/lib/libc.a(shr.o)
     /opt/freeware/lib/libexpat.a(libexpat.so.1)
     /unix
     /usr/lib/libcrypt.a(shr.o)

我已经尝试在我们的 dotfiles 和我们的 mod_env 配置中设置 LIBPATH，但没有运气。我不希望有人知道确切的答案，但我已经没有什么可以尝试的想法了，所以我希望有一些建议可以尝试。

编辑：我还应该指出，使用 XML::Parser 的相同脚本在我们的实时服务器上与普通的 cgi-bin 脚本一样完美。

一个想法：也许您的产品服务器上安装了两个不同的 XML::Parser。您的 CGI 选择一个，而您的脚本选择另一个？

从脚本（在 prod 和 dev 上）和您的工作 CGI 中打印出 @INC 并比较结果。

问候，
