[uber-nerd] does anyone know how to (easily) set up a dns server on os x?

[mattkime]

I'm curious if anyone here knows an "easy" way to set up a dns server on os x. i need my machine to point a domain name toward my machine rather than the machine that everyone else sees - for development purposes. (ACTUALLY....my iPhone needs to see that. otherwise i could just edit the hosts file. and my iPhone is using internet sharing with my mac. yes, its complicated but it keeps me employed)

I'm currently limping along with the help of a linux wielding coworker but i'd prefer to be in control.
