[Pythonmac-SIG] PyObjC ScreenSaver on 10.7

I have two versions of python, so I'll try this twice.  First with the built-in version:
$ which python
/usr/local/bin/python

$ python --version
Python 2.7.2

$ python setup.py py2app
……..

$ file dist/SillyBalls.saver/Contents/MacOS/SillyBalls 
dist/SillyBalls.saver/Contents/MacOS/SillyBalls: Mach-O universal binary with 2 architectures
dist/SillyBalls.saver/Contents/MacOS/SillyBalls (for architecture i386):	Mach-O bundle i386
dist/SillyBalls.saver/Contents/MacOS/SillyBalls (for architecture x86_64):	Mach-O 64-bit bundle x86_64

$ file dist/SillyBalls.saver/Contents/MacOS/python 
dist/SillyBalls.saver/Contents/MacOS/python: Mach-O universal binary with 2 architectures
dist/SillyBalls.saver/Contents/MacOS/python (for architecture i386):	Mach-O executable i386
dist/SillyBalls.saver/Contents/MacOS/python (for architecture x86_64):	Mach-O 64-bit executable x86_64

And with my own build of python:

$ rm -rf build dist

$ which python
/Users/bergs/special-build/Frameworks/Python.framework/Versions/2.7/bin/python

$ python --version
Python 2.7.3rc2

$ python setup.py py2app
…….

$ file dist/SillyBalls.saver/Contents/MacOS/SillyBalls 
dist/SillyBalls.saver/Contents/MacOS/SillyBalls: Mach-O 64-bit bundle x86_64

$ file dist/SillyBalls.saver/Contents/MacOS/python 
dist/SillyBalls.saver/Contents/MacOS/python: Mach-O 64-bit executable x86_64


> Which versions of python, pyobjc, and py2app do you use (and for the python versions, is this the apple provided one or some other install)?


I installed the same version of pyobjc to each python install:

$ python -c "import objc; print objc.__version__"
2.4

$ python -c "import py2app; print py2app.__version__"
0.7.2

The System Preferences app doesn't give a very useful error message ("Contact the developer of this screen saver for a newer version.").  Do you know if there's any way to get a better idea of what's going wrong?  As far as I can tell, Console.app doesn't have any useful output on this problem.

Thanks,
Stuart
