I've tracked this down a bit more: In different Python 
versions were referenced (I have installed Python 2.6b1 with make 

PYTHON_CONFIG = /usr/bin/python2.6-config
pythondir = ${prefix}/lib/python2.5/site-packages

After applying the attached patch it worked. Obviously this patch 
cannnot be considered a solution. It's rather a work-around and I sent 
it along to give a hint where to search for this issue.

Ciao, Michael.
