I was able to make it all work. 

For the record my problem was, as Aahz said in his detailed report of the issue [1], related to py2app and not PyObjC itself. I did build everything from sources so I was expecting everything to work, but it didn't.

The clue was in the stack trace, where you can see "normal" pathnames, like this one...

...and weird ones, like the four last ones:

The reason why it fails miserably is because py2app doesn't seem to know how to deal (or fail to deal correctly) with compressed Python eggs. The solution (at least for me :)) is to force PyObjC and any other library to be installed as non-compressed eggs. I personnally did it by patching all the setup.cfg files with an additional easy_install section, like this: 

[easy_install]
zip_ok = 0
