One more note. I came across this link yesterday:
http://developer.apple.com/library/mac/#qa/qa1666/_index.html
How do I make sure that the ScreenSaver bundle I've created with py2app uses
the correct garbage collection setting? Is there a way to specify
GCC_ENABLE_OBJC_GC=required from setup.py? Also, is there a way to inspect a
binary to see if this setting was used to build it?
Sorry for my ignorance….
Thanks again,
Stuart
