 I can't seem to be able to use the LLVM backend on OSX. I get the error:
 {{{
      error: unknown directive
             .macosx_version_min 10, 0
             ^

 <no location info>:
     Error running clang! you need clang installed to use theLLVM backend
     (or GHC tried to execute clang incorrectly)

 <no location info>:
     ghc: phase `Clang (Assembler)' failed (exitcode = 1)

 }}}

 This is on GHC 7.10.1
