   This usually means that the place where the destructor of the smart   
   pointer is executed can't see the definition of the pointee class.   
   Boost/tr1's shared_ptr will let you do this without exposing the pointee   
   class definition at the point of destruction.  However, it strikes me   
   that if you're using smart pointers to implement a UUID class there may   
   be something wrong with your design.  UUIDs seem like classic value   
   types to me.
