>Description:
Trying to build bittorrent, which pulls in two py-* modules, fails because gcc 
is missing -lpython when building the Python modules.  Adding LDFLAGS+= 
-lpython fixed the build for me in both cases. 

A user reported a smiliar issue to this on teck-pkg on 19/10/04
(20041018215440.3705D14401%tiamat.goathill.org@localhost) but AFAIK did not 
receive a response. 
>How-To-Repeat:
try building bittorrent on OSX with pkgsrc -current.
>Fix:
This is a really bad, slightly tested hack, no more.  Someone who knows more 
about python and how the modules infrastructure works should see if this is the 
correct way to address the issue.
