[Haskell-cafe] Re: cabal: : openFile: does not exist (No such file or directory)

[Mike Pentney]

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

Mike.
