yes... i have the same feeling.. 
but don't know why it should matter

homebrew installs it in /usr/local/Cellar/ghc/7.0.4/bin
but it creates a symlink in /usr/local/bin
so, it's part of the path.

I can try to install it again, with the .pkg that it's available at http://hackage.haskell.org/platform/mac.html

I used to have a lot of cabal problems when running a version of the GHC installed with MacPorts. I notice you're using homebrew. Maybe that's part of the problem?
