fping6 from rpmforge doesn’t work on CentOS 7

I’m running CentOS Linux release 7.0.1406 (Core) and was installing SmokePing.

I added FPing6 to the configuration file and added this as a probe to some websites:

+ FPing6
binary = /usr/sbin/fping6

+ Hosts
menu = Misc

++ somehost
menu = somehost
probe = FPing6
host = www.example.org

After the config changes I tried to restart smokeping but it failed:

# service smokeping restart
Restarting smokeping (via systemctl):  Job for smokeping.service failed. See 'systemctl status smokeping.service' and 'journalctl -xn' for details.
                                                           [FAILED]
