 I'm running Mojave with Xcode 10. I have attached a log file.

 Right, that's the problem you'll see building most any port that uses
 xcodebuild, with new versions of Xcode.

 We need to decide under what conditions to add the `-derivedDataPath` flag
 to the xcode portgroup. Should we add it for Xcode 5 and later, since the
 option appeared in that version? Or should we only add it on the versions
 of Xcode where it fails if we don't, and if so, what versions are those?

 We also need clarity on the scheme issue Ken raised.
