You could use sudo to run the cpan command, but you may want to leave the system perl alone. Did you look at the second link:

curl -L http://cpanmin.us | perl - -l ~/perl5 App::cpanminus local::lib

"This will install either cpanminus and local::lib (and all other required modules) locally into $HOME/perl5 directory."

Follow the other config step which follows and you should be fine. If you look at local::lib it describes the boostrapping technique used.
