Warning: it looks like protoc 3.0.0+ isn't installed on your system,

which means that you won't be able to compile .proto files for use

with gRPC.

If you are just using pre-compiled protocol buffers, or you otherwise

have no need to compile .proto files, you can ignore this.

If you do need protobuf for some reason, you can download and install

it from:

   https://github.com/google/protobuf/releases

Once you've done so, you can re-run this check by doing:

   make verify-install
