From the official ruby-lang.org website
(http://www.ruby-lang.org/en/news/2010/08/18/ruby-1-9.2-released/):

==============================================
It causes a LoadError
    $: doesn't include the current directory. Some script may need
modifications to work properly.
==============================================

I.e., "." is not one of the directories Ruby searches for scripts to
require. Either use require_relative (which doesn't work in IRB, because
there is no source file one could require relative to) or use

require "./yourscript.rb"

But PLEASE do not use that inside normal scripts, that's what
require_relative is made for (and require_relative does some more than
the code I gave above).
