I would make the time for MacPorts. My assumption is just that I still
know to little about how the MacPorts builds work to be of assistance,
and that "you guys" have matters in hand. If you think that I can
actually help, and if there is documentation or source code available,
please let me know. I'm ready for some reading. ;-)
