Comment (by ryandesign@…):

 I've compared your latest log with mine, and there are hundreds of
 differences in capabilities that my system correctly detected that yours
 didn't. I'm hoping comparing the config.log files will explain why.

 Also, please let me know what version of Xcode you're using. If you're
 running less than 6.1, you should upgrade to 6.1, and also ensure you've
 installed the matching Xcode command line tools.
