Did you glide install? The dependency seems to be on the gopath, but should be vendored. Also, use go test (go list ./...) so you don't run test on everything under vendor as well.

As far as I can tell, not a bug. Actually, not even applicable today since we don't use glide anymore, and we do not support Go 1.8 or lower.
