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.

edgar@edgar-ubuntu:~/Desktop/dph$ ghc --make -fdph-par -XTypeOperators ./concomp.hs
[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,
