I'm a complete newbie when it comes to Macs and OSX so I may have approached this all wrong. I just wanted to build the latest version of boost with the latest version of gcc so I can use C++11 features. I never realised it would be so difficult.
The clang that comes with Xcode supports quite a bit of c++11, and depending on release schedules, more than gcc.
[ Right now, I believe that gcc 4.8 is ahead of Apple's current clang release in language features, but libc++ is ahead of libstdc++ in library features ]
