I have this funny relationship with py2app. I like what it produces but it is a real hassle to get working. Anyway, the basic situation is this:

• i needed an application bundle for msatcommander
• you cannot, technically, include the Apple-compiled python in an application bundle
• this means you need to get one from somewhere else (e.g. roll-your-own)
• pyqt4 requires a framework build of python (unless you hack, hack, hack)

Other interesting tidbits:

• you need to keep the architectures of everything produced the same. i chose to stick with x86_64 and i386.
• the prepackaged Qt is built for 3 architectures. This will cause you problems.

Therefore:
