'make integration' not working properly

[aaron-prindle]

In attempting to run the integration tests via:
'make integration'
I encountered the following issue:

$~/go/src/k8s.io/minikube$ make integration
go test -v ./test/integration --tags=integration
# _/home/user/go/src/k8s.io/minikube/test/integration
test/integration/cluster_status_test.go:25:2: cannot find package "k8s.io/kubernetes/pkg/api" in any of:
        /usr/local/go/src/k8s.io/kubernetes/pkg/api (from $GOROOT)
        /home/user/go/src/k8s.io/minikube/_gopath/src/k8s.io/kubernetes/pkg/api (from $GOPATH)
FAIL    _/home/user/go/src/k8s.io/minikube/test/integration [setup failed]
make: *** [integration] Error 1

I was able to run the tests running with:
go test -v ./test/integration --tags=integration

I just wanted to post this as an issue as 'make integration' is currently in our README docs and it doesn't seem to be working for me.
