I really like swatch a lot. Seems like I've been using it for forever. I wrote about it a little bit in this month's MacTech. It also happens to be making an appearance in my presentation this Tuesday.
While swatch compiles and installs cleanly on OS X - even the missing perl packages - some people just like a double-clickable installer. I made one for each architecture, and they can be had here:

Enjoy!
