It was meant to be serious :)

I looked some more and...
The 10.5 SDK doesn't include headers for Python 2.3, so one has to use the 
10.4 SDK for an application using python to work on Mac 10.4.

I guess another option is to copy the Python framework into the application 
bundle, but I'd rather not.
