This means you have an old plugin lying around which is trying to import some things that no longer exist in "twisted.plugin". The traceback is mostly harmless, but you should really re-install Twisted from scratch so that you don't experience other issues related to this, such as spurious test failures. In general I would not recommend using 'setup.py' to install to site- packages directly, because of problems like this; you should use a tool like Combinator[1] or virtualenv[2] to manage your development dependencies. 1: http://www.divmod.org/trac/wiki/DivmodCombinator 2: http://pypi.python.org/pypi/virtualenv _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
