Comment (by jeremyhu):

 Replying to [comment:16 RJVB]:
 > I thought it'd be that one. I also thought I'd left a question on that
 page. Off-topic here but I don't get that change: I'm more used to
 removing proxying through xcrun to make it possible to use other compilers
 than AppleClang. Maybe this targets newer OS versions (than my 10.9)?

 Following up in email on macports-dev instead of here.
