ProtoPackageIsVersion3 is undefined in prometheus/client/model/go

[Liberalite]

Hi everyone ! I'm trying use make deps inside a go project and I get the following errors:

github.com/prometheus/client_model/go ../../prometheus/client_model/go/metrics.pb.go:22:11: undefined: proto.ProtoPackageIsVersion3
