Comment (by kencu):

 clang-4.0 shouldn't depend on clang-3.9. Might you have your
 "default_compiler" in macports.conf set to clang-3.9? If so, try setting
 it back to clang-3.8, which I believe you have installed already from your
 log.

 This doesn't explain exactly why you're getting the errors in the SDK,
 tho. Just trying to get you running.
