[kylemclaren]

FYI @nstott @jipperinbham:

➜  transporter git:(master) go get -a ./cmd/...
# gopkg.in/dancannon/gorethink.v0
../../../gopkg.in/dancannon/gorethink.v0/connection.go:22: undefined: ql2.Response_ResponseNote

Thanks @kylemclaren , try
go get -u ./...
or, go get -u gopkg.in/dancannon/gorethink.v1
-u updates the dependencies of the named packages as well as the packages themselves
