LLVM and clang depend on a pretty modern compiler; the steps below assume you uinstalled GCC 4.8.2 as described above. It should be possible to build using clang >= 3.1, such as what you might find on a Mac, but that will require changes to the way LLVM is configured (specified in src/Makefile) that I haven't tested.
