[Boost-users] Statechart compile error on OS X

I'm trying to use Boost.Statechart in an iPhone development project. When I build the Hello World example in a .mm file (Objective C++) I get an error "error: no class template named 'rebind' in 'struct Machine'". If, in the same project, I build the statemachine in a .cpp file (C++) and call a C function from a .mm file it works perfectly. Is there a compiler flag or project setting that I need to change to get the state machine to work from a .mm file? I would really like the state machine to be a member of an Objective C class.
