Have you installed xcode command-line tools?
And what which clang returns?

Well, I have port installed 7.8.3 as it needs an existing GHC, then I unpacked 7.8.4 from tarball and...............
checking whether bootstrap compiler is affected by bug 9439... You are using a new version of LLVM that hasn't been tested yet!
We will try though...

Is that a problem??? It seems to have run the configure script just fine for all of that.

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.

I'd recommend looking at:

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.

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...

I can't really explain the details of what's going on here. It seems that in some cases different versions of the executables are being found, but I don't know why. Wiping out your sandbox (cabal sandbox delete) and starting over may be sufficient to recover.

As requested,
iMac:~ vosabristol$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.8.3
which ghc
/opt/local/bin/ghc
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!
:)

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

Forgot to add that somehow, despite the upgrade, my cabal version has gone backwards from 1.20.0.1 to 1.16.0
WTF?

I started an OpenGL project within an LTS sandbox as guided on another post and, somewhat foolishly it would see, I did a "cabal install cabal-install" when prompted that a new version was available.
The very next time I tried to work on my code.... I got this:

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