you're probably enabling the "fedora-development" yum repo, which contains
the latest and most unstable. --enablerepo=* seems like a bad idea to me.

rpm --nodeps is not something I would recommend. If you have another tex
distribution that works perfectly with lyx, you probably want to package it in
an rpm format and make sure it provides the same dependencies as the standard
tetex. Then yum won't complain anymore.

Broken dependencies are bad.
