Hey,
Check your $PATH variable. It looks like the macports installation directory
has precedence over /user/local/bin/.
But you also might want to remove the old version installed via macports.

So... there is a possible case for *once again* performing a complete and utter
removal of Haskell and its partners in crime and doing a fresh installation?
Out of frustration I built OCaml and OPAM from sources last night but I'd still
like to go with GHC!

So, welcome to a different kind of hell, "cabal version hell" perhaps?
Can anybody help me get it running again?
Thanks.

Agreed Michael!
I am currently wiping all Mac Ports packages and I will perform a clean up
of /Library/Haskell etc.
What is the *preferred* way to get the lastest for OSX: Using homebrew,
macports or the Haskell Platform. I *used* to use the platform installer
but for some reason (cabal I expect!) I started trying out other ways...
I think actually I will go the platform packager again...
