Installation fails.

Requires python to have zlib module, which is lacking in python-2.5.2-gcc2-2008-11-10.zip

~/Desktop> sh setuptools-0.6c9-py2.5.egg 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
zipimport.!ZipImportError: can't decompress data; zlib not available

note: setuptools is a prerequisite for Bitten ( http://bitten.edgewall.org/ ) as well [wiki:dev-python/pyopengl PyOpenGL].
