This is an unrelated issue to the patch to be tested (that's about
Fortran code), I'm guessing you're on 10.6 here and c++ is version 4.2
(should be 4.0). Try "$ export CXX=/usr/bin/c++-4.0". If this doesn't
work let's discuss offline.

active, which does not have x86_64. So this certainly can't work.
