Comment (by evanmiller):

 Well I am coming over from TigerBrew - I like that Tiger support is
 integrated into the main MacPorts tree, rather than forked off into a
 separate universe. Seems to be easier to get the latest software that way.

 My interests are in testing a few of my C libraries on Tiger / PowerPC,
 since that seems like a good way to uncover endian and platform errors. So
 I've been installing packages to that end. I will submit tickets as I
 encounter errors, and pull requests as I have the time. I intend tickets
 as a means of documentation, but if you would prefer pull requests without
 tickets, I can do things that way. I'll plan to add installation proof to
 future PRs. GTK takes a while to compile, so I just sent it off as soon as
 the configure step was successful.
