maybe you should install brightbox's ruby1.9.1
sudo apt-get install ruby1.9.1
$ apt-cache show ruby1.9.1 | grep Version

I guess, p194 was the current version when 12.10 was released. You'll only get security updates for your packages (if the maintainer takes care about this). If you want to get the latest version automatically, you should not use release-based linux distros (like debian,ubuntu, rh,...). It's not the philosophy behind releases, that you'll get bleeding edge versions for everything. I'm using archlinux for several years now, which has a rolling (i.e. no) release cycle - it's not perfectly stable, but I always get the latest version for most of the packages, e.g. ruby: https://www.archlinux.org/packages/extra/x86_64/ruby\.
