Typing habits, I capitalize the first letter, so that should be forks.pm in the first line as well 
$ perl -v

This is perl 5, version 22, subversion 1 (v5.22.1) built for x86_64-li

I may be doing this part wrong;

    You did. The command should be:

    cp /usr/local/lib/x86_64-linux-gnu/perl/5.22.1/forks.pm .

      ...and this is wrong:

      perl -E 'BEGIN[unshift @INC, ".";} use forks'
              ^

      That bracket [ should be a brace {.

      However, as anonymonk pointed out, it's much cleaner to write it as:

      perl -I. -E 'use forks'

      Mea culpa, I shouldn't be making simple typos like that. Round 2: 
      $ cp /usr/local/lib/x86_64-linux-gnu/perl/5.22.1/forks.pm .
$ perl -I. -E 'use forks'
Argument "2.53_01" isn't numeric in numeric ge (>=) at forks.pm line 1

        Not sure how relevant it is to your problem but that message is described in this bug report

        This is more of an issue now that the latest stable perl version is using a version of Storable which triggers this warning. From 5.22.01 perldelta:

       Storable has been upgraded from version 2.53 to 2.53_01.

        Hi,

        As a general rule copying files around is not the way to solve directories missing from @INC
