That's not quite true, we actually run with -p macosx_16_i386. And
certainly you can reproduce the problem by setting os.platform to
anything other than "darwin"...

% port info glfw os.platform=macosx
Error: process_cmd failed: can't read "portinfo(version)": no such
element in array

portindex is supposed to set os.platform=darwin and
os.subplatform=macosx in this case, but I guess that's broken?
