Provided correct versions are in place.

In my aforementioned observations, Gem installation was complicated when the parent app relied on gem versions below the code currently in GitHub.

This is of course a problem not unique to Ruby (see: Default Python version on CentOS), based on the number of versioning utilities for Go. I have also had plenty of problems with autoconf's that don't work.
