Comment (by ryandesign@…):

 Wait, you said using the setting in comment:22 did not help, with
 (referring to [ticket:51322 your ticket]) Xcode 7.2.1 on Yosemite? It
 fixed the problem on my Yosemite system with Xcode 7.1.1. Let's wait and
 see what the [https://build.macports.org/console buildbot] does.
