[Pythonmac-SIG] Multiple python 2.5 framworks

[Ronald Oussoren]

Even if you don't use py2app you should have a look at macho_standone  
(part of macholib). This is a script that will make an application  
bundle standalone by embedding the frameworks and dylibs used by an  
application into the app bundle.

Py2app is however the easiest way to build standalone application  
bundles for python applications, although some tweakage might be  
needed to deal with Qt (IIRC Bob removed the Qt recipe because it  
didn't work correctly with recent versions of Qt; building a new  
recipe or just including all of Qt into your app bundle should be  
easy enough).
