Seriously Jules...I know you are light years ahead of me on all this but
what this means is that I have to shut down MailScanner to update perl,
which I have had to do twice this week. When I've got a major update
like CentOS 5.3, that's a significant amount of downtime (though I
suppose I can break out the perl updates separately, it just adds
something else to the hassle factor).

and it seems unnecessary to have to rebuild all of the source rpm's when
they are already built from the last install process.

watching the words "I have to force installation of File-Temp. Sorry."
float across the screen is a nice way of saying...deal with it.
