Yes, the gcc tool chain is responsible for supplying the correct
'-rpath' arguments to ld in order to find the C++ library at runtime.
On occasion I have had to do this by hand, but ultimately it's a
broken gcc installation.

It gets tricky with platforms like HP-UX, where it's easy to reset the
run-time loader path inadvertantly (and thereby lose the C++ library).
I'm pretty sure ELF systems don't have that problem.
