 I have downloaded:

 ghc: ghc-7.6.0.20120810-x86_64-windows.exe

 mingw64:
 http://www.drangon.org/mingw/mirror.php?num=2&fname=mingw-w64-bin-x86_64-20120807.7z

 llvm64:
 http://www.drangon.org/mingw/mirror.php?num=2&fname=llvm-3.1-w64-bin-x86_64-20120610.7z

 my path contains:

 {{{
 /c/ghc/ghc-7.6.0.20120810/bin:/c/Users/Cetin/AppData/Roaming/cabal/bin:/c/llvm/bin:/c/mw64/bin
 }}}


 When I run:

 {{{
 ghc -fllvm --make Main.hs
 }}}

 I get:

 {{{
 [1 of 1] Compiling Main             ( Main.hs, Main.o )

 <no location info>:
     Warning: Couldn't figure out LLVM version!
              Make sure you have installed LLVM
 }}}

 Attached is the output from:

 {{{
 ghc -v3 -fllvm --make Main.hs
 }}}

 for all Main.hs - it mentions:

 {{{
