We renamed the -XPArr language flag to -XParallelArrays. There was a patch to ghc-head that you'll have to pull or port across. We're still actively working on DPH, and changes to the compiler often entail changes to the libraries. If you haven't branched the libraries then your build is going to break on a weekly basis. Ben.
