That commands comes with distribute, but not setuptools. Can you tell me, are you on a Debian or Ubuntu (or other Debian-based) OS? If so, I don't know what's going on, but if not, I suspect the problem is the line: from setuptools import setup, find_packages On Debian, setuptools is really distribute, so it all works, but on non- Debian derived systems, this is probably broken. ** Changed in: mailman Status: New => Incomplete ** Changed in: mailman Importance: Undecided => Low -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1035061 Title: setup.py build_sphinx is broken To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1035061/+subscriptions
