Thanks for the reply. You think like I do: figure out how it SHOULD
work, and then deduce the route to get there!

Problem with this route, is that it screams the parts of mysql are
needed by the other packages: that is, the dependencies go both ways.

Unfortunately mysql is not, to my knowledge, available through yum. I
got the upgrade to work however, by using 'rpm --force -U MySQL'.
I think that is failed previously because I put the --force -after- the

This route can get really messy. If I went that way, I would find the
old versions and copy the new ones into the same spots.
What is really weird about this is that the RPM's are from mysql.com and
they install the program in a completely different manner than the
Install procedure set out in the tar.
