I have maybe the same/similiar error (qt5.0, boost 1.52). After including

#include<boost/uuid/uuid.hpp>

#include  <boost/uuid/random_generator.hpp>

in a qt-header file, I get the error

boost/mpl/if.hpp(131): Error: Macro argument mismatch.

during compiling of the correspondence moc_...cpp file. It looks like a 
preprocessor error message...

Cheers
