CentOS - Oct 2007 - why type "perl -MCPAN -e shell" -> "install XML::Simple" on CentOS 5?

I'm running nmap2nagios.pl, and I notice that on CentOS 5, I had to
run the following to get it working (when I didn't have to do the same
on CentOS 4)

perl -MCPAN -e shell
(answer questions)
> install XML::Simple
Why is that?

Because for some insane reason you chose to go about things the hard
(and potentially dangerous) way instead of 'yum install
perl-XML-Simple' from the base repository.

Please don't make me get out my soap box regarding package management.
