Gems is pretty self-contained - gems can depend on other gems, with a
variety of versioning  options. If you try to install a gem that
depends on others, you will be asked if you wish to install those
first (unless the correct versions are already present on your
machine).  I use Windows so there isn't any other packaging system for
it to interact with.
