Centos 4.6 post Yum update / perl-IO - Watch it!!!!

[Alex Broens]

On a running MailScanner 4.69.8 / Centos 4.6 box, after "latest yum 
upgrade" MailScanner refused to start due to

**** ERROR: You must upgrade your perl IO module to at least
**** ERROR: version 1.2301 or MailScanner will not work!

a "cpan upgrade IO" fixed it BUT as others have stated, if we start 
seeing frequent module version issues, Julian's "easy & safe" package 
becomes questionable.

comments?
