[haskell-llvm] problem installing llvm with cabal

[Nathan Howell]

Grab the clang/llvm binaries here:

http://llvm.org/releases/2.9/clang+llvm-2.9-x86_64-apple-darwin10.tar.gz

and put them somewhere... I put it in /opt/clang-2.9. Then install the
bindings like so:

PATH=/opt/clang-2.9/bin:$PATH cabal install llvm

Cabal will pick up the 2.9 llvm-config and bake the paths into the
installed package. This shouldn't conflict with the 3.0 bits that come with
Xcode.
