I do not believe that 'chef_gem' is being phased out. Opscode could
confirm -- Perhaps the documentation author (one of my team mates)
meant that the 'chef_gem' Heavy Water cookbook would no longer be
required post 10.12.0 or so.

In some states, you may have deployed Chef via gem to an embedded
system interpreter. In this case, the chef_gem cookbook,
omnibus_updater and gem_installer cookbooks will allow you to
transition to newer cookbooks that use the 'chef_gem' method of
installing a gem to the embedded Opscode Chef interpreter instead of
the system interpreter (which generally requires another Ruby
installation).

In some states, you may have deployed a system and an updated Chef
'full stack' omnibus installation may have been released, again, our
cookbooks will help.

In alternate states, you may have deployed multiple rubies to a single
system and require the capability to install gems to any-which of
them; again, our cookbooks will allow you to achieve this.

I can't possibly know which of these states your infrastructure is in;
I leave the adventure up to you :)

I neglected to mention one, possibly helpful in the event you require
a system Ruby installation [0]
