util/docker_registry/dummy_client.go:80: 
cannot use func literal (type 
func("github.com/opentable/sous/vendor/github.com/stretchr/testify/mock".Arguments) bool
) as type 
func(                                 "github.com/stretchr/testify/mock".Arguments) bool 
in argument to drc.Spy.MatchMethod

My spies package (github.com/nyarly/spies) leverages testify/mock, because the interfaces are similar.

Because I'm using my local copy of `spies` and also have vendored testify/mock, I get this conflict.
The solution is to vendor my spies package, which is inconvenient when trying to develop the support package in tandem.
