[CentOS] CentOS-5.3 yum-priorites

I visited http://wiki.centos.org/PackageManagement/Yum/Priorities which tells me to install the package yum-priorities available from extras. I try this and it fails.

# yum install yum-priorities Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * addons: mirror.csclub.uwaterloo.ca * base: mirror.csclub.uwaterloo.ca * extras: mirror.csclub.uwaterloo.ca * updates: mirror.csclub.uwaterloo.ca Excluding Packages from CentOS-5 - Base Finished Excluding Packages from CentOS-5 - Extras Finished Reducing rubyworks to included packages only Finished Excluding Packages from CentOS-5 - Updates Finished Setting up Install Process No package yum-priorities available. Nothing to do

So, where has it gone?
