I had a similar problem (on Ubuntu Incontinent Ibex). I'd previously installed ghc 6.8.x, and (among other things) cabal. When I decided to upgrade to the Haskell platform, I deleted ghc but not my original cabal installation.

When I got the error, I deleted my (old) copy of

~/.cabal/config

and it seemed to fix the problem. I'd assumed something in the config file was pointing to a file or directory that had been removed when I uninstalled ghc 6.8.x...

HTH

lol, yep you're right. I'd assumed the haskell platform shipped with the latest parsec, when in fact it does not :) my bad...

However, I fixed the cabal issue by installing ghc 6.10.3 and rebuilding the haskell platform. Apparently there is either a compiler issue or incompatibility with 6.10.4 that causes the cabal: : openFile: does not exist (No such file or directory) error.

did you verify parsec-2.1.0.1 exports

Text.Parsec.Language

?

This might be a parsec 2 versus parsec 3 issue

ghc-pkg describe parsec-2.1.0.1

should tell you the answer to that.
