I would love to help make this happen - the current bjam/Boost.Build  
system for OSX
seems to be getting crappier and harder to make work rather than  
better and easier.
Obviously, the natural way to distribute Boost on OSX is as a single  
Universal Framework.
I'm no expert in the area, but would be willing to expend some effort  
on this, especially
if there is some support on the CMake side...
