He's just helping out in debugging why his py2app-ed application bundle doesn't work, and the py2app bootstrap code looks in the system lib-dynload directory when it shouldn't.

Why it does so is unclear at the moment, I'll have to reproduce the problem (which should be easy enough) and then find a solution.

BTW. Is anyone going to pycon this year? I'll be around until the end of the sprints, although I intend to do some sightseeing as well.   There's two things I'd like to work on during the sprints: work my way through the open issues in python's bugtracker (and get familiar with the new mercurial workflow while I'm doing this), and work on improving the test suites for macholib, modulegraph and py2app.
