Comment (by michaelld@…):

 There is a very strange mix of missing symbols, some of which are
 "`std::FOO::`" and some of which are "`std::__1::FOO::`". The latter are
 used exclusively by libc++, while the former are used exclusively by
 libstdc++. Thus, it seems like no matter the best of intentions on your
 end to try to force using libc++, that 'port' is making use of both of
 these C++ runtimes. It's not clear to me if this is happening just within
 the octave build, or maybe if this comes from some dependency/ies. Octave
 builds fine on 10.9+ using libc++, so I don't see why it wouldn't do the
 same on 10.8 when tweaked to use libc++. That said, if you haven't done
 the "official" tweak for 10.8 and prior to use libc++ then I suggest you
 uninstall everything (again), do the tweak, then try installing octave
 again. I'm really not sure I can help much more here, at least not with
 more info on your 'port' setup.
