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

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

WTF?

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