This is the "known good" problem.  I'm pretty convinced that adding some
kind of "PyPI subset", where gardeners for a given "package set" keep
the list of packages / versions known to work well together, is the only
way out of this issue.  E.g., a URL like:


would be usable as an 'index-url' for setuptools:  when used this way,
setuptools would only find / install eggs from the "gardened" set,
rather than whatever anyone happened to have uploaded that day.

If PyPI can't be tweaked to provide such a feature, we may need to come
up with some kind of mirroring scheme which does allow it.
