Comment (by mschamschula@…):

 Update:

 Reviewing the main.log file I've found that MacPorts was not passing my
 desired compiler (i.e. +gcc48 - macports-gcc-4.8) on to octave, hence the
 build was using Apple clang! - with the same results as llvm3.5.

 I see that the Portfile defines {{{default_variants-append +gcc48}}} , but
 there is no corresponding variant. Am I missing something here? Is the
 +gcc48 variant defined by MacPorts?

 I just built octave 3.8.2 using (in my case mp-gcc48 is selected):

 {{{sudo port install octave +atlas configure.compiler=macports-gcc}}}
