Interesting Torben. I didn't know about DarwinPorts.
DarwinPort's Portfiles resemble FreeBSD's Makefiles and the port structure is alike.
http://darwinports.opendarwin.org/darwinports/dports/
http://www.freebsd.org/cgi/cvsweb.cgi/ports/
This would mean that it would take time, but it may not be too hard to create the "missing" Mac installer. Especially since aolserver and postgresql (and a FreeBSD port) are already there and there are good DarwinPort docs.
So I agree, it definitely looks like a useful project to see if DarwinPorts will really run on Mac, Linux and FreeBSD as they suggest (and how hard it is).
