so long as you include the library / gem in ur script then so long as 
they have that library / gem installed, they shouldnt have a problem, if 
they dont have it installed then the program simply wont run....if the 
user of the script has any idea of how the script works they should be 
able to easily look at the top few lines to ensure they have the proper 
libraries and/or gems installed.

require 'gem_name_or_library'
###
if they dont have it installed, they will get a LoadError..

on the flipside if u wanted to "check" if they have it installed just 
use a
raise LoadError approach
