It seems to be that boost/greg_month.hpp includes boost/shared_ptr.hpp, 
which uses boost/detail/shared_count.hpp which uses 
/boost/detail/lightweight_mutex.hpp.  The pthread symbols are in 
greg_month.o, so it looks like that library won't work without threads 
or else something's supposed to turn threads off but isn't working...
