the package dev-python/zc-buildout from the python-testing overlay (file-)conflicts with net-zope/zcbuildout from the official tree. as both ebuilds seem to package the same piece of software this comes as no suprise :-) it is pulled in by dev-python/zc-recipe-egg-1.0.0. i suggest removing package dev-python/zc-buildout and updating its reverse dependency. Reproducible: Always
+ 1 to remove zc-buildout from python-testing overlay). Per 246085, I was informed that net-zope/zcbuildout is in the portage tree, so that should take precedence. Per 272498, a version bump is requested.
Reassign for the eventual fixes on python-testing overlay
Closing as there is no dev-python/zc-buildout any more in overlay "python", which overlay "python-testing" was merge into.
