Is that error from running yum-complete-transaction?   If not, install
yum-utils and run yum-complete-transaction.  If it is,  I think it
means that your rpmdb shows 2 versions of yum installed and it is
refusing to fix it.   I'd try a 'yum update yum' to make sure you
really have the latest, then 'rpm -q yum' to see if it shows 2
versions installed, then 'yum remove' the full package-version name of
the older one.  And if yum still refuses, try 'rpm -e' with the older
package version.
