This is an old post but still did not have current best practices on RPM-based distributions. Using yum will work for most modules
> sudo yum install 'perl(Perl::Module)'
example
> sudo yum install 'perl(DateTime)'
Not every Perl package is package but
> cpanspec -b dist.tar.gz
will make it for you then you can install with
> sudo yum install /path/perl-dist.rpm
