I've recently picked up a Mac Mini, my first move into the mac world. Of course one of my first tests was to see if Raven would compile. It didn't, but I was surprised at how little work it took to make it (hats off to cmake, macports, and llvm).
I will now be testing builds on linux x86 and x86_64, and OSX.
In addition to committing a patch that fixes the build on OSX, I've updated the tree to include the latest lexertl release, as well as removing the "driver" library, which was unnecessary and integrated into the IR library.
