Using the 1.36 beta libs on OS X and linking to libboost_system-gcc40-1_36.a and libboost_filesystem-gcc40-1_36.a I get :

  "boost::system::error_code::message() const", referenced from:

      boost::system::system_error::what() constin main_mpi.o

      boost::filesystem::basic_filesystem_error<boost::filesystem::basic_path<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, boost::filesystem::path_traits> >::what() constin main_mpi.o

ld: symbol(s) not found

 Any ideas what I'm doing wrong here?
