With

dp.property("node_id", boost::dummy_property_map());

I get: "error: invalid use of void expression".

with

dp.property("node_id", boost::static_property_map<Graph::vertex_descriptor>());

I get: "error: no matching function call to
boost::static_property_map<unsigned int>::static_property_map()"

with

dp.property("node_id",
boost::ref_property_map<Graph::vertex_descriptor, std::string>());

I get: "error: no matching function call to
boost::ref_property_map<unsigned int, std::basic_string<char>
>::ref_property_map()"

Round 3 :) ?
