I believe you do not want the () after the word component_t. In my
examples I do not have 

                boost::property_map<Graph_Base::Graph_t, boost::vertex_name_t>::type clist
                    = boost::get(boost::vertex_name, m_graph);

I think you want the line to read:

    Graph g;
    ComponentPropertyMap vertexToComponent = boost::get(component_t, g);
