Not sure exactly what would cause this, but I would suggest doing a clean re-install of grpc and protobuf. Check out the steps detailed in the comment thread of https://github.com/grpc/grpc/issues/10909. There are a few more steps needed to install protobuf than the ones you mention.
Also, would suggest uninstalling the brew version of c ares and installing the one in the third_party directory, just to ensure that the installed version matches the one the code.
