Pkgsrc on OS X
Well, I got this Powerbook and all the included OSS software was laughably out of date. I could have done the Fink thing, but I like pkgsrc...
My OS X machine is a 12" Powerbook 1ghz PowerPC G4 with 768mb of RAM and a 40gb disk running OS X 10.4.

Here's a guide to get you started. I'd recommend you download the pkgsrc tarball from NetBSD's FTP server instead of checking out CVS (unless you like wasting time).
