I had a problem with this using XDarwin in December of 2001. To fix it, I
set the HOSTNAME variable to my desired hostname in /etc/hostconfig. (It
was set to -AUTOMATIC-).
It's worked fine for me for over a year. I prefer it since I think of my
machine by it's given name rather than by whatever name maps to the IP
address DHCP gave me.
