Yes Setuptools makes some assumptions on how distutils APIs are called
and in which order. Once bitbucket is up, you can look at the details
on the fix
I did, it's fairly simple.
Notice that this has been fixed in Ubuntu already with a patched version
of setuptools, but the next probable step is to use Distribute there
and in debian.

Yes that's the simplest way to fix the problem.
Notice that setuptools patches distutils in other places, and it will
not work with Python 2.7 and 3.2
where Distribute does.
