error with package ghc-6.10.1 and its dependency on process-1.0.1.[01]

[allan]

Dear all

I'm attempting to install the latest haddock version via 'hackage' and I'm getting the error:
Resolving dependencies...
cabal: dependencies conflict: ghc-6.10.1 requires process ==1.0.1.0 however
process-1.0.1.0 was excluded because ghc-6.10.1 requires process ==1.0.1.1

I tried re-installing ghc, but I get the same problem.
Any suggestions?

regards
allan
