Hello.
yep, solving rpm dependencies can be quite a problem. that's why I switched from a redhat based distro to ubuntu which is debian based, where installing software is a breeze thanks to apt-get.
I'm not really suggesting that you should do the same but try reading this article. it just might help you, cause it sure did help me.

sorry if my post didn't address to your problem directly but you can't blame me for not trying.
