Or we VERY clearly and loudly state in the release notes and anywhere else
we can that Distribute has replaced setuptools and everyone should upgrade
immediately because of critical bugs like the one under discussion.

I should also mention this bug was not unknown. I discovered it after
Distribute 0.6 was released as I always run cutting edge interpreters. Never
bothered to report it until Distribute 0.6.1 was released which Tarek fixed
in less than a week. I never bothered to report it for setuptools as I know
it isn't maintained.

It's probably in our best interest to just get people over to Distribute,
let it continue to hijack setuptools, and slowly let that name fade out if
it is going to continue to be unmaintained. I have to admit I find it really
disheartening that we are letting an unmaintained project dictate how we fix
a bug. I really hope this is a one-time deal and from this point forward we
all move the community towards Distribute so we never feel pressured like
this again.
