You'll have to rewrite the loader commands of at least the command- 
line interpreter. I guess the easiest way to do that is to use a .app  
bundle and macho_standalone (part of macholib): Create a (dummy) .app  
bundle by hand and use sys.executable (not the python command) as the  
executable of that application bundle. Then use macho_standalone to  
copy all libraries and frameworks used by the application into the  
application bundle, this will rewrite the loader command's as well.

It might be possible to use py2app to do all the work, that depends on  
how you application is set up.
