checkout a somewhat tutorial here: https://github.com/rdp/ruby_tutorials_core/wiki/gem (https://en.wikibooks.org/wiki/Ruby_Programming/RubyGems)

it shows how to install different versions of dependencies depending on what version of ruby the installee is using.

(short answer--it ain't as easy as it should be)
