It looks like pip parses this and picks the link for the chosen version (or sorting, maybe with distutils.version.LooseVersion, and choosing the highest: the list of links is not sorted). I guess the PortGroup needs to emulate this behaviour.

The python-1.0 portgroup doesn't seem to be involved in the download process at this time. It's all handled by the pypi fetchgroup, right? (In _resources/port1.0/fetch/mirror_sites.tcl)
The pypi fetchgroup also looks for files on files.pythonhosted.org, and that works, right? If so, why does it need to also look on pypi.python.org?
