I figured I'd write up a guide to building Mono from Subversion in preparation of the upcoming 1.2.6 release, on a site I've neglected since I set it up, mononews.org (I hope to get back to writing tutorials and "newsy" stuff with the 1.2.6 release).

Anyways, if you've got Leopard installed, Geoff Norton did a great job in helping me track down the remaining Leopard/i386 bugs earlier today, so now you can build and run Mono relatively easily from Subversion on your fancy smancy new OS.
