production server we don’t use CPAN if we can avoid it. Instead we install RPM
packages of the modules. The main reason is that we want to have repeatable
server builds. It also helps you need the code to be portable to “stock” Red
Hat systems.<o:p></o:p></span></p>

<p class=MsoNormal>Then, whenever you install via cpan, it will use sudo to
install modules. <o:p></o:p></p>

<p class=MsoNormal>That causes cpan to accept the default answers to any
prompts as it installs the CPAN bundle. This is usually so I don't have
to repeatedly answer "y" to install required modules.<o:p></o:p></p>

I got IT at work to install Perl 5.10.1 on a server. I want to update<br>
the modules for all users. I've had an odd amount of trouble finding<br>
info on the Proper Way to upgrade -- maybe my Google-fu is weak today.<br>
Is it as simple as "sudo cpan upgrade"? Should I worry about<br>
upgrading CPAN itself first, if necessary, and if so, how? Are there<br>
any modifications due to<br>
Red Hat Enterprise Linux Server release 5.4 (Tikanga)<br>
