Adding modules without root⚑

$ wget -O- http://cpanmin.us | perl - -l ~/perl5 App::cpanminus local::lib 
$ eval `perl -I ~/perl5/lib/perl5 -Mlocal::lib` 
$ echo 'eval `perl -I ~/perl5/lib/perl5 -Mlocal::lib`' >> ~/.profile 

$ cpanm --interactive -v Mail::Sendmail # Install modules using cpanm

Add this in your code:

use local::lib q(~/perl5);

Everything will be in ~/perl5 (which can be copied to another host)

Alternatively:

$ perl -MCPAN -e shell
