Hi,
I have tried to compile an example of DPH (Data prallel Haskell) but I am not getting any success. The target is the concmop.hs (http://darcs.haskell.org/ghc-6.10/packages/dph/examples/concomp/) for calculate connected components in a graph. I am using GHC 6.10.4 compiled with extras libs (which also includes DPH 0.3.0). I've got this error. Seems that GHC can't find these functions/types.

Perhaps that file is just missing an import? IIRC these things are from Data.Array.Vector, from the uvector package. -Brent
