You beat me to it :)
However, your patch has slightly different semantics from mine: if
bdist_egg fails to import, the rest of setuptools is still used. I
don't know if that's safe. My patch would consider /any/ failure in
the setuptools imports as a complete setuptools failure, and revert
out to basic distutils.
Let me know if you want me to put in my code instead, here's a patch
from my code against current svn (after your patch), in case you'd
like to try it out.
Cheers,
