Building Ruby, Rails, Mongrel, and MySQL on Mac OS X
Dan Benjamin has updated his awesome instructions for Hivelogic - The Narrative - Building Ruby, Rails, Mongrel, and MySQL on Mac OS X. I’ve used these instructions in the past and they work great. The advantage of his method is that you compile the software from source (don’t be afraid it’s really easy) so you have great control over your configuration and upgrades will be easier.
Sakuzaku has a script to automatically download and install the software mentioned in Dan’s Hivelogic tutorial. (Actually, it follows the tutorial almost verbatim.) It’s a great time-saver for people who already know what they’re doing and don’t want to follow the directions one-by-one.
