I am assuming that you have a broken 18 install that you can still boot
to a log-in screen.

I had the same problem with rawhide packages that I was testing. I was
able to fix everything in a failsafe session. Once "yum check" was good,
I was able to install everything without a problem. 

You might want to check yum grouplist and see what is says is
installed.
