[Haskell-cafe] Error in installing dph-examples on Mac OS X 10.7.3

[mukesh tiwari]

Hello all
I am trying to install dph-examples on Mac OS X version 10.7.3 but getting this
error <http://hpaste.org/57699>. I am using ghc-7.4.1.

Error running clang! you need clang installed to use the LLVM backend
cabal: Error: some packages failed to install:
dph-examples-0.6.1.3 failed during the building phase. The exception was:
ExitFailure 1

I have already installed Xcode 4.2 and it shows
