Bug confirmed, I've removed binary distribution for Mac from PyPI.
It seems that the setuptools did not handler the bdist_dump distribution correctly. I’ll check this.

Bug is closed since v0.2 is released, and binary package for OSX is canceled in this version. Binary package for OSX will be published when the upstream Distribute project start supporting for OSX binary executable format.
