There isn't cjdns in openwrt 15.05.1

Only luci-app-cjdns. Should I do downgrade to 15.05?

For some reason it was not included upstream. I don't know why. So, you can try building it yourself for 15.05.1

Yeah okay, looks like I didn't pay attention there. Anyhow, whatever the issue was, it seems fixed now.
