What about this port requires Xcode 8.3 or newer? Are you sure it isn't instead a requirement on a specific version of clang? If the latter, use the compiler_blacklist_versions portgroup instead. macOS 10.12 is the minimum requirement for cquery-devel as `shared_timed_mutex` isn't available until then. Xcode 8.0 to 8.2.1 might work, but I have no way of testing it. All the other issues have been addressed at https://github.com/macports/macports-ports/pull/2000
