normal yum upgrade procedure

Additional info:

Went to #fedora-devel for help. Mistake. Google search and found suggestion

sudo rpm -e yum yum-metadata-parser --nodeps

Then rpm.pbone.net search to find earlier versions

sudo rpm -ivh yum-3.1.2-1.fc7.noarch.rpm yum-metadata-parser-1.0.3-2.fc7.i386.rpm

And, back in business, able to update other packages, e.g., gcc, kernel, etc.
