I don't see anything in those packages that should be creating
undefined references to boost::system.  roscpp uses boost::system, but
only internally, and libros.so is linked against libboost_system,
which should work fine.

I could provide more help if you send the verbose output from trying
to build your package:
 VERBOSE=1 make
