Debian, and most distros derived from it, try to factor out
dependencies as much as humanly possible.  It's not a matter of being
arrogant and thinking, "We know better than you how to distribute
ruby", it's a matter of allowing someone who doesn't care about ruby
to install the very minimum required to run a program that itself
requires ruby.

Even with the advent of broadband, this is still very important, as a
number (probably a majority) of users are still in countries where the
default is metered connections, and every extra byte costs them money.
Also, such fine (and orthogonal) dependencies allow people to create
custom LiveCDs and/or distributions that contain only what they need
(yes, a number of people use Debian as a base for embedded Linux
programming for that very reason).

However, feel free to ask the ruby maintainer to change his packaging;
he may agree with you.
