Hello,
this patch adds a run-time import hook for PyOpenGL. Details are explained
in comments in the file, so can be read there.
This patch has been in my local tree for several months now with optimal
results. It's convoluted, but works.
Commited as r218.

+# PyOpenGL (specifically, OpenGL.__init__) reads a "version" text file
+# containing the version number to export it as OpenGL.__version__. When
+# packaging with PyInstaller, the 'version' file does not exist, and importing
+# PyOpenGL results in an IOError.
+# The (convoluted) solution is to override Python's builtin "open" with our
+# own function which detects when "version" is opened and returns some fake
+# content stream (through cStringIO).

+ # Restore original open, since we're almost done

+ # Report a fake revision number. Anything would do since it's not

+ # separated by dots.
