[Pythonmac-SIG] py2app PyOpenGL "Unable to find an implementation" Error

[David Selassie]

I'm trying to package up a program I wrote that uses
PyOpenGL-3.0.0b4-py2.5.egg, numpy-1.1.1-py2.5-macosx-10.3-ppc.egg
installed with easy_install and PIL. I know there's been a bit of
trouble getting PyOpenGL scripts to play nicely in py2app, but I have
not been able to find any help about anyone that has run into the
error "RuntimeError: Unable to find an implementation for the 'darwin'
('posix') platform". Generating the app file runs without complaint
but this error occurs when trying to run the program.

Does anyone have any suggestions as to the cause or what to do?

The console log is as follows:
