OK, I think I fixed it. I had mosh installed, which depended on protobuf-cpp, but nothing else.
I uninstalled mosh, and checked that nothing else depended on protobuf-cpp (nothing did). I uninstalled protobuf-cpp and installed protobuf3-cpp, and then reinstalled mosh (which is happy with protobuf3-cpp). Now the upgrade outdated is happy.
