when i'm installing the glx driver it says this do i need to worry about it?

I would have to say no don't worry about it... Its just a warning letting you know what it was doing... It was just renaming some driver files so the ones the rpm was installing wouldn't conflict with the ones that the installation found.

I haven't ever ran into this before but thats what it looks like to me.
