Sorry about the lack of information available.  There's a sample of 
usage here (known to work on Win32 and Linux with latest CVS HEAD):

http://pyopengl.cvs.sourceforge.net/pyopengl/OpenGLContext/tests/shaderobjects.py?view=markup

The key information you seem to be missing are that the Python version 
has a simpler API and that you have to pass an array (list) of strings, 
not just a single string to the compilation function.  The count and 
length (array of lengths) parameters are pulled from the list-of-strings 
you pass.

HTH,
Mike
