Took the bulk of the day off today to get the next release of PyOpenGL out the door. I've re-enabled the numarray support, using the same underlying library as for the Numeric support (i.e. no binary modules). I've also stripped out the "Demo" directory and made a separate egg for that so that projects that just want to include the code don't have to strip out the Demo to get it done.
Don't have a Win32 or OSX machine handy on which to test. Install does work on a Kubuntu Linux machine, though. Anyway, for the vast ravening PyOpenGL hordes:
easy_install -U PyOpenGL
Should update to the latest version.
