I am a 30+ years hacker Boris, building from source might just tempt me
still!! HAHAHA
My machine is now "clean" so I will decide how to play it!
Thanks again everybody.

Hey,
Little addition to what Michael already sent you.
To get ‘the latest’ you should build from sources :D
But in case it’s ok for you to have ghc 7.8.3 and you don’t want to ./configure; make; make install, you might also check this installation script on github https://github.com/yogsototh/install-haskell.

I don't generally recommend using the platform installer, it ends up pegging libraries to old versions which causes dependency problems, or in some cases have known bugs.

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...

Hmm.... it shows a macports instsallation of GHC... but I am sure that's how I git it... I *used* to use the OSX installation package but I thought a clean start using MacPorts would somehow change the mood...
iMac:~ vosabristol$ cabal --version cabal-install version 1.16.0.2 using version 1.16.0 of the Cabal library
iMac:~ vosabristol$ which cabal /usr/bin/cabal
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!
:)

wrote: Funny that there's an issue being discussed in the cabal issue tracker right now[1] similar to this. But the report you're giving here is particularly strange. Cabal-1.16 implies that you're using GHC 7.6, which is supported by the claim that base 4.7 isn't available. I'd recommend starting off with running the following commands and pasting the output:
ghc --version which ghc cabal --version which cabal

WTF?
