Hi,

Hi all, I'm unable to cabal upgrade with the following error: Resolving dependencies... cabal: 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
I am currently running ghc 6.10.1 and process 1.0.1.1. It's a bug of Cabal. I think developers will fix this problem in the feature.
Now you can do below step for fix this problem: 1-> execute command "ghc-pkg list" Find same package from two list, and use command "ghc-pkg unregister PackageName --force" remove same pacakge. 2-> execute command "ghc-pkg unregister procss-1.0.1.1 --force" I think that's okay. And don't use "cabal upgrade" command until developers fix this problem. If you want install some package, please use command "cabal install" -- Andy
