[Haskell-cafe] Bug in Cabal?

Hello haskell-cafe, trying to install ghci-haskeline I got the following error message: $ cabal install ghci-haskeline Resolving dependencies... cabal.exe: dependencies conflict: ghc-6.10.1 requires process ==1.0.1.1 however process-1.0.1.1 was excluded because ghc-6.10.1 requires process ==1.0.1.0 Looks like this is a bug in Cabal or cabal-install? Regards, Martin.
