The OSX build has been broken ever since the new std.regex was merged in: 
http://d.puremagic.com/test-results/

You can read the discussion about it on the pull request: 
https://github.com/D-Programming-Language/phobos/pull/310  It sounds like it's 
a compiler bug, but I don't think that they've quite figured it out yet.
