Comment (by cjones051073):

 I completely agree that the xcode variant should be made the default on
 mac OS 10.13 (and newer...). At least until Apple releases newer version
 of the source to allow the tool kit it installs to be updated. As it
 stands the ld64 port installs binaries built using Xcode 8 vintage code
 (the latest currently made open source by Apple) and in fact are older
 than the Xcode 9 used on 10.13.

 Note, for the record, we need to do the same for the cctools port, which
 has exactly the same issue as ld64 (and might become more of a problem for
 MacPorts in the future).
