I think you should first of all make sure it's been installed. For this you should get something from this:
rpm -L | grep <whatever>
comes from 'whatever.rpm'. If that doesn't work try just
and check if whatever
appears in the list.
If the whatever
appears in the list whether by using the first or the second way, then try:
Afterwards, you might re-check that the whatever
doesn't appear in the list by using any of the previous ways.
Since I'm not very like the most appropriate person to help about this, I encourage anyone who knows more than me about this to write his/her solution.
