Message 83112 - Python tracker
For more info, see discussion starting here: <http://mail.python.org/pipermail/python-list/2009-March/703067.html> I suspect a difference in the proxy configuration available between OS X and OS X Server, although I don't have a OS X Server configuration at hand to test it. (For 2.6, the OS X proxy configuration code was rewritten to use ctypes instead of the deprecated mac Carbon wrappers.)
