Ok, I've experimented some more and came to some sort of conclusion in the bug report: http://tinyurl.com/yaa23yl The warning problem occurs if the environment (which you mention above) uses distribute. This environment could be a buildout egg cache. If a buildout, which uses this cache, only knows about setuptools (as there's no distribute depencency in that buildout), you'll get the extra "hey, I already loaded this" UserWarnings. But, and that's the mostly-good news, these warnings only occur if you have a global setuptools and haven't installed distribute globally yet. In that case, somehow there's a fallback to the global setuptools which omits those warnings. IF warnings THEN install it also globally, basically. And, from what I see, a global install works just fine with a buildout that doesn't use the new bootstrap. Provided the setuptools in the egg cache has been patch already by some other buildout :-) Reinout -- Reinout van Rees - rein...@vanrees.org - http://reinout.vanrees.org Software developer at http://www.thehealthagency.com "Military engineers build missiles.
