Comment (by kencu):

 Well -- anywhere that modules are enabled. It's probably an Xcode test, I
 guess, rather than an os.version test we will need -- I'm sorry, off the
 top of my head, I'm not 100% certain which Xcode started supporting
 modules. I think we just have to do some trial and error unless someone
 can find the tiny little page on the internet that tells us...
