need some help understanding a linux error message

[mcveigh]

I'm getting mail for root with the message

/bin/bash: /usr/bin/mrtg: No such file or directory
from the crondaemon every five minutes.

now in /etc/crontab i have this line
0-59/5 * * * * root /usr/bin/mrtg /etc/mrtg/mrtg.cfg

I didn't put it there, so I'm not sure what that's about.
I just reinstalled the OS (RH 7.2) on new hard drives on monday night.
I copied most of my /etc/ over and all has been well on the user end.

any ideas

EDIT:

this is /etc/mrtg/mrtg.cfg
Is this a standard base install package? I don't remember ever putting a package like this on... no need to
I'm going to comment it out of etc/crontab and see what happens
