Someone complained on IRC that buildout's tests are failing. You can see the same failure on Travis: https://travis-ci.org/buildout/buildout/jobs/46070031#L97

The commit that triggered that build appears to be unrelated to the failure.

Last successful build on Travis was 22 days ago and used setuptools 8.0.4. The failing build uses setuptools 11.3.

I'm pretty sure the following setuptools change broke buildout's dev.py: Moved pkg_resources into its own package.

Bitbucket makes it hard to see which releases contain that commit. GitHub makes it easy: every release since setuptools 8.3.
