ffi-compiler gem is completely untested according to its maintainer's comment here, so it's not surprising at all that a new release breaks protobuf installation.

@acozzette I think this is probably a good reason to prioritize #15555 to remove ffi-compiler and rake dependency.

ffi-compiler 1.3.2 fixed the issue.
