Comment (by AgilentGCMS):

 I want to use the macports-installed compiler because in my experience
 clang is usually a few builds behind the official GCC releases, and lacks
 certain features. E.g., clang, at least on my mac, does not support
 openmp. This is not to say that python requires openmp, but since I
 compile everything on my system with the gcc installed by macports, I
 wanted to have a consistent system. My idea is that it *should* work, even
 though it's not recommended.

 I'm attaching the config.log, sorry for not attaching it earlier.
