I can clear up the "why", but don't yet have a solution.  Basically, the 
various application-building systems, such as py2app, py2exe and 
cx_freeze don't yet support the setuptools/egg format properly.  They 
neglect to properly register the bundled-up eggs, so the 
setuptools-based plugin code (which handles the array formats) never 
gets registered or invoked.

At the moment I have no solution for this.  I'm planning to sit down at 
some point and try to figure out a patch for the various tools, but my 
available time for OpenGL hacking is minimal these days and I'm still 
focused on the core functionality, more than the packaging issues.  I 
*believe* with certain approaches with py2exe it should be possible to 
exclude the library entirely and then just drop the .egg into the 
application's distribution directory, but I haven't tried that and 
haven't confirmed that my understanding is correct.  I'm guessing you 
would need to be sure that setuptools is included in the bundle as well, 
btw.

Good luck,
Mike
