From my comments:

Due to a more strict linker included with Xcode 4, this is disabled on Mac OS X and iOS.  The reason? It changes the visibility of Boost functions.  The mismatch between visibility Boost when used in Ogre (default) and Boost when compiled (hidden) results in mysterious link errors such as "Bad codegen, pointer diff".
