That's probably your second or third option.
Your first step should be to check whether the module is packaged by
your distribution. For example, if you were running Debian and wanted
to install XML::Parser, you'd say something like
aptitude search '~dXML::Parser'
and you'd find out that it's in the package called libxml-parser-perl,
so you'd then say
aptitude install libxml-parser-perl
to install it. That way, you won't be the one spreading infectious code
when a vulnerability for the Perl module you forgot that you're relying
on gets out, because it'll get updated with the rest of your system.
(I've already had the an Indonesian host donning an XML Slapper worm
Halloween costume knocking on my door. It was denied both trick and
treat, but the admin responsible got a get-well-soon e-mail. That could
just as well have been a Perl module vulnerability.)
For the above reason, if your distribution doesn't package the modules
you need, change to one that does. (Ha ha, only serious.)
Your second option would probably be to use a tool that turns the module
into a package for your distribution, if such a tool exists. Once
again, in Debian, you'd first install dh-make-perl and then run
dh-make-perl --build --cpan Module::Name
