Compiling doesn't work on macs

[jpalmer]

So in theory it should be possible to compile the code on a mac.

There are some issues:

1. the mac uses clang instead of gcc (and it is clang that tries really hard to pretend to be gcc).

2. how to get the dependencies working.

3. is basically solved as we can use clang on linux

4. is more difficult - but should be possible through homebrew

Some annoyances that I have found, stuff like including open gl requires special flags and you include slightly differently

e.g.

 include <opengl.h>

to

 include <GLUT/opengl.h> (or something like that)
