You could add a selective work-around that just triggers if setuptools
has been loaded on the 2.6 branch.

if sys.modules.has_key('setuptools'):
   # monkey-patch fix-up setuptools to work with the new code

or the other way around:

if sys.modules.has_key('setuptools'):
   # undo r1234 to make setuptools 0.6c9 happy again
