error with snap

[micruzz82]

When trying a go get on another repo, I get the following error

github.com/intelsdi-x/snap/pkg/schedule

/root/go/src/github.com/intelsdi-x/snap/pkg/schedule/cron_schedule.go:64:12: undefined: cron.Parse
/root/go/src/github.com/intelsdi-x/snap/pkg/schedule/cron_schedule.go:82:7: assignment mismatch: 1 variable but c.schedule.AddFunc returns 2 values

Is there anyone who can help to fix this?
