The situation was that a user had a version of setuptools installed
(I think it was v0.6c5), and the ez_setup.py specified setuptools
v0.6c6 (which was at that time the current version). So, when the
user executed "./setup.py", then he got an error saying that it
wasn't possible to upgrade setuptools after setuptools was already
With our patch, this is no longer a problem -- v0.6c5 is new enough
to work, and so the setup.py execution proceeds after the check
without attempting to install a newer version of setuptools.
