For some reason, Perl is being forgotten by companies - irrespective of the power of the langurage - and preference for Python.
You can use the following command to download CPAN to build a local CPAN repository.
$ cd $HOME $ mkdir CPAN $ /usr/bin/rsync -av --delete cpan-rsync.perl.org::CPAN ./CPAN . . ..
Once it is downloaded, you need to change the urllist to search this directory. It needs to be a complete URL - otherwise, it will not be accepted.
cpan[1]> o conf pushy_https 0 cpan[2]> o conf urllist push $HOME/CPAN
