This happened to me after I removed yum-conf-sl7x package after updating
to RC1 (why? Well, that's how I interpreted release notes
http://ftp.scientificlinux.org/linux/scientific/7.0/x86_64/release-notes/
- that I should remove that package to get proper updates after RC
release).

It breaks like this after that, and one has to write "7.0" into
/etc/yum/vars/slreleasever to fix it. Why release notes say that we
might need to remove that package and break the system? Not sure. Maybe
it's to remind people that this is beta/RC stuff which is expected to
break and no one will care :)
