I always go by what the modules say they need as pre-requisites, not 
what happens to appear to work. There may be some nasty edge case that 
you haven't tested.

Have you any suggestions for how to avoid this problem entirely? One 
possibility is to use CPAN to install the modules that I otherwise have 
to --force. But that still totally screws with the RPM installation of 
Perl itself, it just does it in a way that is hidden from 'perl -MCPAN' :-(
One other possibility is to much with the installation setup of each of 
my required Perl modules, so that they are always installed in the 
"site" tree which should be out of the way of CPAN and RPM. Not sure how 
easy it is to do that though. Any thoughts?

Sorry, I have had a good look. When I upgraded some other Perl module, 
it must have complained that it needed an even newer version of the IO 
module than shipped with RedHat 5 or CentOS 5, as that's what I build on.
