[haskell-llvm] problem installing llvm with cabal

[Philippe Sismondi]

Nathan: I think I replied to you off the list earlier today. Sorry.

Anyway, it appears that you are right. llvm-config reports that I have llvm version 3.

It strikes me that this is something that the cabal install stuff and/or the autotools stuff should be checking for, no?
