Comment (by dtakahashi42@…):

 Thank you very much for upgrading the port, and for looking my patches.

 Here, the upgrade to 1.16 did not help. Still I cannot compile gsl with
 +gcc47 +optimize, due to the AVX instructions. Could you check your cpu
 architecture? The "-march=native" problem only appears when gsl is
 compiled on OSX machine with Sandybridge, Ivybridge, and Haswell cpu. Here
 is a list of machines with those cpus (from wikipedia).
 * Macbook Pro: early 2011 or later
 * Macbook Air: mid 2011 or later
 * iMac: mid 2011 or later
 * Mac mini: mid 2011 or later
 * Mac Pro: currently none.

 The option affects only on those machines, and harmless for others.
