This package is in severe violation of PKGBUILD standards. It's bad
enough when mysteriously complicated software only works with giant
ruby-bundler envs installed in /opt. But under no circumstances should
it be installing its own dependencies into /usr/lib/ruby/gems

Indeed, non-slotted packages might be needed by other software expecting
up-to-date versions, so this is strictly inferior to option 3.

This is a suitable workaround if the package cannot be updated to use
the latest version. But try to see if upstream can update their code to
be compatible with the latest versions of their dependencies...
