Some newbie help

Can anyone help out a Linux newb with this error?

Execution of '/usr/local/sbin/fping -Ae' failed - program not suid root?

I am migrating our monitoring from BB installed on Windows to Hobbit on Linux. I was able to successfully install FC4, all of the Hobbit subcomponents, and Hobbit. Just this one error has me stumped. I thought I corrected it by adding hobbit to the WHEEL group on FC and then editing sudoers file to uncomment WHEEL, but I still have the error.
