Never mind. I bypassed the problem by source compiling the Gazebo Harmonic and use the packages being compiled in the way.

We don't pin the protobuf version in the homebrew formula (see https://github.com/osrf/homebrew-simulation/blob/5f50a0c8a72624157fd77357f8803a4b229636b1/Formula/gz-msgs10.rb#L23), but it might be that a new protobuf was released after we built the bottle. The bottles were rebuilt yesterday, so maybe you need to reinstall. Building Gazebo from source like you've done would also work.
