py2app is using setuptools too, supporting a minimum Python version of
2.3.0. It was MUCH MUCH simpler than using distutils directly.
Additionally I borrowed the sdist script from PyObjC that ignores
subversion junk.

Yeah, I was pretty sure that this was the case. You simply just
specify that you want to include PEAK as a package (which includes the
whole package as-is, outside of the zip file). At some point I'll add
a recipe that detects the presence of PEAK and makes this happen
automatically, like I do for pygame, but I'm going to wait a bit until
I hear about other packages so I can just do them all at once before
the next release.
