How do I "specialize boost::property_map directly"?  This might be the key to the problem.  
My current shot in the dark is to try:
template<>
struct boost::property_map {
typedef EdgeWeightMap type;
typedef EdgeWeightMap const_type;
};
which gives me the error
implicit.hpp:116: error: specialization of ‘template struct boost::property_map’ in different namespace
/opt/local/include/boost/graph/properties.hpp:244: error:   from definition of ‘template struct boost::property_map’
You need to do:

namespace boost {
   template <>
   struct property_map {
     ...
   };
}
