I've merged the revision 4 patch into a git repository at
http://git.geekfire.com/?p=ports.git;a=shortlog;h=python25

It's on top of a fairly recent version of ports, with all conflicts
resolved.

I'm concerned that we haven't fixed the problems that were found during
pointyhat runs, portmgr@ wants this to be built on pointyhat before it
goes into ports. I think we should be careful to make sure we've fixed
the known build failures and then have pav@ do a pointyhat run for us.
