Code:
[root@polideukis dev]# rpm -qa | grep yum
yum-2.3.2-7
Do "rpm -e yum-2.3.2-7" to uninstall and then download the same version from a server and install it using "rpm -ivh yum-xyz". "rpm -F" , where F means freshen might work also. I don't know what u want to do. Read "man rpm". That might help.
