Changing operating system is always challenging, I knew exactly how to do
it when changing between FreeBSD, OpenBSD and Linux,
but I was sure Mac OS X would be harder. It was.
I wanted to use DarwinPorts because it looked like
what I was used to and had more packages available than Fink.
port failed to find the PostgreSQL
libraries, and poking around in the system uncovered no solution, So I
fired off an email to the DarwinPorts
mailinglist and Markus Weissmann fixed it.
So now everything works again and life is good.
