Compilation issue with vendoring

[opoudjis]

As of a couple of days ago, I can no longer compile nats-streaming-server (could do so two days ago, cannot do so now):

# _/Users/nickn/Documents/arbeit/go/src/github.com/nats-io/nats-streaming-server
./nats-streaming-server.go:156:24: cannot use nOpts (type *"github.com/nats-io/gnatsd/server".Options) as type *"github.com/nats-io/nats-streaming-server/vendor/github.com/nats-io/gnatsd/server".Options in argument to "github.com/nats-io/nats-streaming-server/server".Run
./nats-streaming-server.go:177:2: cannot use natsOpts (type *"github.com/nats-io/nats-streaming-server/vendor/github.com/nats-io/gnatsd/server".Options) as type *"github.com/nats-io/gnatsd/server".Options in return argument

I'm struggling to work out what has happened, and there are no commits in the intervening period that impact nats-streaming-server.go.

One thing that I did find is that there are nested vendor directories in gnatsd, which are known to confuse build:

./vendor/github.com/nats-io/gnatsd/vendor/github.com/nats-io/nuid
./vendor/github.com/nats-io/gnatsd/vendor/golang.org/x/crypto/bcrypt
./vendor/github.com/nats-io/gnatsd/vendor/golang.org/x/crypto/blowfish
./vendor/github.com/nats-io/gnatsd/vendor/golang.org/x/sys/windows/registry
./vendor/github.com/nats-io/gnatsd/vendor/golang.org/x/sys/windows/svc

However blowing away the nested vendor directories does not make the error go away.

Sorry, false alarm: I was getting the issue identified in https://stackoverflow.com/questions/41319633/vendor-folder-not-used-with-go-build
