Octave builds and runs great on older systems right now when they are upgraded to libc++ per the current instructions.
$ port -v installed octave The following ports are currently installed: octave @4.2.0_1+accelerate+app+docs+fltk+gfortran+graphicsmagick+qt4+sound platform='darwin 10' archs='x86_64' octave @4.2.0_2+accelerate+app+docs+fltk+gfortran+graphicsmagick+qt4+sound (active) platform='darwin 10' archs='x86_64' Rather than force the older systems to install gcc6 and libgcc and then find a roundabout and complicated way to support cxx11 with c++ standard library inconsistencies, I would suggest we finally just change/add/modify/get the buildbots to libc++ once and for all and be done with that. IMHO it would be a lot less trouble to do that than it will be to go through the trouble of working through all the ramifications of yet another standard library on these systems.
