Hmm, you *should* be able to use the PyOpenGL-accelerate .exe installer,
it was built with Python 2.6 (since that's the only thing that can build
a binary extension for itself).  PyOpenGL is cross-version, so it
doesn't necessarily get built with the current version (which I think
was the problem here).  The source install of PyOpenGL-accelerate
requires a C compiler, which is a large download for Win32 systems.

HTH,
Mike
