Smart Pointer Usage with derviable class?

I have a class that I want to derive from in lua, with a smart-pointer
like container but I'm getting template compilation errors and I can't
figure out what's missing. Actor has a private constructor, but Actor_w
and ActorId do not.

class ActorId {
 // blah blah
// other stuff here too but this is the end result of *id
 Actor *operator *() const { return a; }
 // blah blah
};

void initActor() {
// blah blah
	module(L) [
	 class_<Actor, Actor_w, ActorId>("Actor")
         .def(constructor<>()) // this line causes failure, see below
// blah blah
	];
}

If I remove the .def(constructor<>()) line it compiles fine, so I'm not
sure what I'm missing here.

Errors are here:

This is with VS2010 Pro edition, boost 1.42.1, and luabind 0.9.
