I think that easy_install and related tools can be directed to the proper download location by providing a Download-URL on the PyPI page. E.g. the page for Twisted 9.0.0: http://pypi.python.org/pypi/Twisted/9.0.0 should have a Download-URL link to: http://tmrc.mit.edu/mirror/twisted/Twisted/9.0/ Regards, Ziga _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
