[Haskell-beginners] Problem to compile an example of Data Parallel Haskell

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.

[1 of 4] Compiling Graph            ( Graph.hs, Graph.o )

Graph.hs:11:45: Not in scope: type constructor or class `:*:'

Graph.hs:23:6: Not in scope: `hPutU'

Graph.hs:33:15: Not in scope: `hGetU'

Using the example from Ben Jao Ming 
(http://overtag.dk/wordpress/2009/04/data-parallel-haskell/), I can 
successfully compile and run.

Could anyone help me?

Kind regards,
