[Haskell-cafe] ghc/dph

Hi, I want to use dph (data parallel haskell) for a presentation. (Nothing fancy, just compile and run some demos.) What ghc version should I use and where do I get it? I read the advice "use HEAD" but when I build from the 7.1.20101213 source snapshot, dph is not installed (should it be?) Best - J.W.
