I am not the author of this software and it is rather complex. I know that it 
links against Boost.Filesystem and Boost.Regex and that this is enough for 
boost-1.40 or 1.41 installations but seems to be not enough for boost-1.46.0.
Searching for boost-related includes in the source-files yields the following:
boost/algorithm/string.hpp
boost/filesystem.hpp
boost/graph/adjacency_list.hpp
boost/graph/breadth_first_search.hpp
boost/graph/connected_components.hpp
boost/graph/filtered_graph.hpp
boost/graph/graph_traits.hpp
boost/graph/graph_utility.hpp
boost/graph/graphviz.hpp
boost/graph/johnson_all_pairs_shortest.hpp
boost/graph/reverse_graph.hpp
boost/graph/strong_components.hpp
boost/graph/visitors.hpp
boost/property_map.hpp
boost/regex.hpp

Does any of those require Boost.System nowadays?
Thank you.

Best,

Cedric
