Problem running PyObjC/py2app app on machine without PyObjC installed

Hey, all. Long time no see.

So, I've revived one of my PyObjC apps (Zem), but am running into problems getting the resulting app to launch on systems that don't already have PyObjC installed. This hasn't so far happened with my other PyObjC apps, so I'm wondering if I'm just doing something wrong.

  Here's a link to the py2app-built binary: http://swng.it/nP7QK

  Here's the code: https://github.com/orangutango/Zem/

I could tell that some things had changed in the PyObjC/py2app worlds since the last time I heavily used them.

I built this bundle the standard way:

  $ python setup.py py2app --iconfile Resources/Zem.icns

(Incidentally, I'm not sure why it doesn't pick up on my Info.plist entry for CFBundleIconFile, but whatever)

The error I get on machines without PyObjC installed is:
