Summary: glProgramParameteri is undefined

Initial Comment:
glProgramParameteri is undefined. This makes usage of geometry shaders impossible.

The error happens here:

File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/OpenGL/platform/baseplatform.py", line 344, in __call__
    self.__name__, self.__name__,
OpenGL.error.NullFunctionError: Attempt to call an undefined function glProgramParameteri, check for bool(glProgramParameteri) before calling


A workaround for the windows platform can be found here:
https://sites.google.com/site/dlampetest/python/geometry-shaders-from-python
and here:
http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=277436

Unfortunately I couldn't find a workaround for the mac or linux.
If you have questions or a tip for a workaround, please write me: pyopengl [at] pdietrich.net

Cheers!
Patrick
