How to retrieve list of installed module (or gentoo bad installation ?)

[mathieu.malaterre at gmail.com]

Hello,

   I am trying to build an executable that link against python
libraries. If I only link to python lib I get thoses errors(*). This
machine is a gentoo AMD64. I installed python by doing 'emerge python'
and my USE flags uses 'zlib'.
   I am wondering if there is a 'python-config' like script that would
tell me that I also need to link against zlib libraries in order to
properly link my executable ?

   Has anyone seen this problem before ? Or is this simply that there
is a misconfiguration problem in my gentoo installation ?

Thanks for your advices,
Mathieu
