Checking the latest PyObjC doesn't mean you must ship it. The bug may
be fixed in SVN head, that would save us a lot of time :-)

BTW. I don't see why you couldn't ship a version of PyObjC inside your
app bundle. If you're running user scripts in a seperate interpreter
you should make sure that the stuff in your bundle isn't on the search
path, users scripts should only see system-wide stuff.

BTW2. Relying on a user-installed version of PyObjC is bad: what if
PyObjC 1.7 breaks PyOxide and an unsuspecting user installs that. I'd be
very surprised if a standalone application breaks because I install a  
new
library.
