cabal build all

With the release candidate build of cabal this works great! Full disclosure that I didn't follow this entire process as I got a good chunk of the way on my own but I was getting stuck with errors around llvm not being installed when running the build. Your lines 31 - 33 fixed that for me. Many thanks!

Heads up for anyone trying this... this took about 6 hours to build but it's working great now that it has!
