You might want to add a few lines describing how to add the appropriate 
yum repository so the user doesn't see:

[root at somehost ]# yum install denyhosts
Gathering header information file(s) from server(s)
Server: CentOS-3 - Addons
Server: CentOS-3 - Base
Server: CentOS-3 - Extras
Server: CentOS-3 - Updates
Finding updated packages
Downloading needed headers
Cannot find a package matching denyhosts
No actions to take
