Hi, we're trying to use pants v1.3.1rc0 for compatibility with Mac OS 10.13, but getting the following error:

Exception message: Failed to fetch binary bin/native-engine/mac/10.13/ab51a617f069641eb6b47e8713e51150ad0a6ab0/native_engine.so from any source: (Failed to fetch binary from <https://s3.amazonaws.com/binaries.pantsbuild.org/bin/native-engine/mac/10.13/ab51a617f069641eb6b47e8713e51150ad0a6ab0/native_engine.so>: Fetch of <https://s3.amazonaws.com/binaries.pantsbuild.org/bin/native-engine/mac/10.13/ab51a617f069641eb6b47e8713e51150ad0a6ab0/native_engine.so> failed with status code 404)

I guess there's some missing overlap between https://github.com/pantsbuild/pants/pull/4894 and https://github.com/pantsbuild/pants/pull/4806. What's the best way to resolve this issue?
