Moving my development environment from Debian to OS X

As of yesterday, I have managed to make the transition from doing all my development on the Linux box in my cubicle to doing it on my Powerbook instead. This is very convenient, as it allows me to work, not just from home, but from just about anywhere I am. Of course, since Xcode, Apple's revolutionary new IDE, is not available for a few more weeks, I'm still stuck using the old Project Builder for the next little while.
