 MacPorts is adding the -arch flags: because it believes it's going to be
 using a compiler that supports them. The problem that needs to be fixed is
 that octave-gsl is using gcc46 at all, not that -arch flags are being
 passed to it.

 During the configure step, mkoctfile (built by the octave-devel port) is
 called to get the CC, CXX, etc flags from the octave installation. As
 octave-devel was built with +gcc46 (CXX=g++-mp-4.6), this is what is
 returned. It's here in the configure stage that it complains. octave-gsl
 basically inherits the compiler from the octave(-devel) port, and that
 uses gcc46!
