Comment (by ionic@…):

 Thanks for uploading the log file. Without it, no help is possible.

 The error is different from what I've ever seen, but it's possible that
 the instructions on the Problem Hotlist wiki entry relating to Xcode 7.2
 help here as well: [[ProblemHotlist#xcode7.2]]

 No guarantee, but the main meat is that xcodebuild crashes. The port
 itself should be fine and I cannot workaround that issue there either.

 Please try executing the suggested changes, than `sudo port clean
 pinentry-mac` and retry your previously failing operation.
