If you happen to use PyFacebook on Gentoo you probably noticed that djangofb.py didn’t create/copy any skeleton files for the Facebook application to be created (for an example how it should work, take a look at the PyFacebook tutorial).
In order to fix this, just download my update of the pyfacebook-9999.ebuild. This updated ebuild reflects PyFacebook’s move to GIT for versioning (from SVN), hence ensuring that you always use the latest available (‘official’) sources with latest fixes (among others, some changes to /pyfacebook/setup.py to fix the djangofb problem). I also recommend to watch the forks of PyFacebook for recent changes.
