Comment (by ryandesign):

 This is a new error as of clang 15. We don't see the problem on our
 buildbot workers because we don't use the newest version of Xcode on the
 macOS 13 builder.

 If `-Werror` had not been used, it would just be a warning, not an error;
 it's recommended not to use `-Werror` in ports for reasons such as these
 (new compilers being stricter than older ones).

 I don't see any attempt in the log to fetch our binaries, so perhaps you
 forced a build from source? If you allow our binaries to be used, you
 won't encounter this error.
