MAC OS X support for arbtt

[vrasneur at free.fr]

Hi, 

I have some code that makes arbtt work with MAC OS X.
The changes are available in a git branch: https://github.com/vrasneur/darcs-mirror-arbtt/commit/e2a138ae865a68bd1b9117f41a1f5ea881995e71

Can somebody with a Mac test that arbtt works correctly with his computer?

Here are the compilation instructions:

First, you need the Haskell platform for Mac.
You also need:
* git
* a package manager for OS X. I use MacPorts (https://www.macports.org/) but it should work with Homebrew.
* XCode and the XCode command line tools

Note: the OS X port itself does not need a C/Objective-C compiler. It uses the Haskell FFI to call the Mac OS X specific functions.

then, 

* install the C dependencies with your package manager
sudo port install pkgconfig
sudo port install pcre

* clone the OS X git branch
git clone -b osx-support https://github.com/vrasneur/darcs-mirror-arbtt/

* use cabal to build/install arbtt
cd darcs-mirror-arbtt
cabal install --only-dependencies
cabal configure --extra-lib-dir=/usr/lib
cabal build
cabal install

The option "--extra-lib-dir=/usr/lib" is necessary because of a conflict with iconv. (See http://blog.omega-prime.co.uk/?p=96 for a detailed explanation)

* then, go to /Users/<user>/Library/Haskell/bin/ and type ls
You should see all the arbtt binaries.

* then, you can execute the binaries:
cd /Users/<user>/Library/Haskell/bin/
./arbtt-capture&
./arbtt-dump
