AMP itself isn't doing anything clever that I can see would confuse 
py2app.  It's just a regular Python module with regular imports; no 
dynamic module loading; in fact, it's much less interesting than the 
core parts of Twisted which load various plugins.

I don't have any experience with py2app, but I can guess at the problem 
- I know that OS X 10.5 ships with an incomplete installation of Twisted 
in some system location.  Perhaps you've installed a complete version of 
Twisted elsewhere, but py2app is confused about the ordering of sys.path 
that you want, and is including the system location first.  I am not 
aware of how this installation is incomplete - maybe it doesn't include 
AMP?

However, this is only a vague understanding, I don't have a MacOS Python 
environment readily available to test with.  Twisted might actually be 
packaged inside one of Apple's application, not on the system path, so 
this could be a red herring.  Good luck investigating though, and please 
let us know your results when you discover what's going on!
