This is most probably not a problem with GCC itself, but with using it
(and the linker), so your question would be better handled at
<gcc-help@gcc.gnu.org>.

Some additional hints were somewhat useful, like

  * Which compiler and linker is used? For which platform? MacOS I
    guess?
  * How does the final linker call look like?
  * How does your dynamic linker configuration look like?
    Specifically: Is your libboost_serialization-1_34_1 in the
    library search path?

Most probably.

You need to tell the dynamic linker where to actually find the
libraries. "stage/lib/..." looks like a relative path, but to what
location?
