Unfortunately, you need to add "USE_GCC=any" to math/octave/Makefile,
and rebuild it.  You theni need to run "ldd -a | more" and search for
shared libraries that are linked against both libc++ and libstdc++.
Then, add "USE_GCC=any" to those ports' Makefile and recompile.
I recall at least 4 that needed to be rebuilt, but only remember
fltk and libgraphite2.
