Improving the Python build system.

[Cyril Roelandt]

Hey!

Andreas, could you please send us your Python modules that fail because 
of setuptools ? I think these packages require setuptools instead of 
distutils (which comes with Python), so we'll probably have to package 
setuptools. Both are quite similar, so the "python-build-system" can 
probably be used anyway. Otherwise, we'll have to write a build system 
per tool (distutils/distutils2/setuptools/bento).

Cyril.
