Hello,

$ cabal install category-extras 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

What does this message mean? It makes little sense to me -- ghc-6.10.1 requires both process ==1.0.1.1 and process ==1.0.1.0?

And, more importantly, how do I solve this?

ghc-pkg unregister process-1.0.1.1 . If that fails, rm -r .cabal .ghc . If that fails, fix cabal ;) -- (c) this sig last receiving data processing entity. Inspect headers for copyright history. All rights reserved. Copying, hiring, renting, performance and/or quoting of this signature prohibited.
