It's shorter and you don't have to spawn a ruby process to print
something, if you can use the gem command directly.
I'm not a TU so take my this with a grain of salt, but I don't think
this is the best advice.
It's shorter, admittedly, but `gem` spawns a ruby process just as the
`ruby` version does. Using gem doesn't work however when `$GEM_HOME` is
set, since then it reports the contents of that variable.
Especially for AUR packages using `$(ruby -e'puts Gem.default_dir')` is
more convenient since most users do not build in a clean chroot, and the
wiki actually recommends settings that environment variable so quite a
few will have it.
