ValueError: A 0.7-series setuptools cannot be installed with distribute [But we're on 20.7 now]

When running buildouts bootstrap.py, setuptools generates the error below. This version is 20.7. It looks as if a regex meant to screen for version 0.7 is triggering an error for version 20.7? This is breaking all builds, please help.

ValueError: A 0.7-series setuptools cannot be installed with distribute. Found one at /tmp/tmpIFxckv/setuptools-20.7.0-py2.7.egg

Confirmed. We have to hack up gevent-psycopg2 to not use distribute_setuptools and had to upgrade pycassa. gevent-psycopg2 is unmaintained and we happen to be using it in production:(.

Can we release quickly 20.8.0 just to avoid this problem for the community? And also have a safeguard to never release any version that will have '0.7' in the version string?

oh, that's terrible! Yes.

So, wait, let me get this right... This problem was fixed by simply bumping the setuptools version from 20.7.0 to 20.8.0, and pretending this will never be hit again?

I understand you can't fix all setuptools versions out there that have this hard check on '0.7' in the version string, but at least you can put something in place to make sure you don't reintroduce this issue later?
