And you showed the output of "gcc --version" which made me think you were using gcc to do so. If so, you'll need to switch to using clang to compile that other software, to match how MacPorts has compiled opencv.

That's if you're on 10.9 (10.8?) or later... But that just boils down to using the system compiler, which ought to be the case if you don't specify one yourself.
