Comment (by gnwiii@…):

 For me, after uuninstalling octave (built with {{{+gcc5}}}), "{{{port
 install octave}}}" worked on Mavericks and El Capitan, but fails on Snow
 Leopard (10.6.8 using the Apple C++ runtime):

 {{{

 I assume this is [https://trac.macports.org/wiki/LibcxxOnOlderSystems
 Libcxx on older systems].
