For that mater how can I get yum installed?  I downloaded yum 2.6 source did make make install and it seemed to go OK, but I get the following error:
 
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
 
   cannot import name Errors
 
Please install a package which provides this module, or
verify that the module is installed correctly.
 
It's possible that the above module doesn't match the
current version of Python, which is:
2.3.4 (#1, Sep 26 2006, 17:25:54)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-3)]
 
If you cannot solve this problem yourself, please go to
the yum faq at:
  http://wiki.linux.duke.edu/YumFaq
According to what I can see, it is the correct version of python for this version of yum.

Subject: Red Hat EL4 - Expired Subscription - How to update

Ok, I want to continue updating this machine, and I am just to lazy to strip REL4 off of it.  How can I release upto date from the locked (No Channel Associated) redhat network and over to Cent OS's update network?
