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

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 -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
