Are you sure you started with a clean environment? In a bzr trunk checkout (try `bzr clean-tree --ignored`) I did the following: $ virtualenv /tmp/xx $ source /tmp/xx/bin/activate $ python setup.py install $ buildout $ bin/test Everything worked and all tests succeeded. The other thing is that I'm not even sure if buildout is supposed to be compatible with virtualenv. Assuming it is, I'm still thinking about getting rid of buildout support for the final release. The hang up right now is replacing zope.testrunner. -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/869347 Title: bin/test script fails unless zope.testrunner is pip installed To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/869347/+subscriptions
