Johnny, 
Thanks for the pointer, I did have a CentOS-Base.repo.rmpnew file. 

I am still unsure what is happening with yum. I am getting this now:

Loading "protectbase" plugin
Loading "installonlyn" plugin
/usr/lib/python2.4/site-packages/yum/plugins.py:380: DeprecationWarning:
registerOpt() will go away in a future version of Yum.
Please manipulate config.YumConf and config.RepoConf directly.
  DeprecationWarning)

Unfortunately, the documenation on the web site for yum does not cover
Centos5.
