Could it be that the cabal gets confused because there are two
versions of Cabal-1.6.0.1 but which probably depend on two different
versions of process?

Hi
Thanks for the reply, here is a small terminal session with the commands you suggest as well as "ghc-pkg list"

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?
Hmm, that's odd. It makes it look like the ghc api package depends on two different versions of the process library.
The output of "cabal install -v haddock" might give us more of a hint. That and "ghc-pkg field ghc depends"
