Error running clang! you need clang installed to use the LLVM backend
However with ghc-7.2.1 , It compiles and run.

Macintosh-0026bb610428:tmp mukesh$ ./Hello
Hello Haskell

It may be a problem with the gloss / opengl dependencies? do you have those packages installed?

Hello all
I am trying to install dph-examples on Mac OS X version 10.7.3 but getting this error. I am using ghc-7.4.1.

This probably isn't DPH specific. Can you compile a "hello world" program with -fllvm?
