LLVM compilation not working with Haskell on Yosemite

Question

I'm trying to use llvm with haskell and I'm getting the error "illegal hardware instruction"

Details:

I'm compiling a simple hello world program just to test it out:

Code:

module Main where

main :: IO ()
main = putStrLn "Hello World"

GHC version 7.10.1, llvm version 3.4.2 (older version because haskell doesn't work at all with 3.6.1).

Command to compile: ghc -O2 --make firstProgram.hs -fllvm -fforce-recomp

Exact error with command ./firstProgram

[1] 23665 illegal hardware instruction ./firstProgram

Thanks for any help!
