Installing Ruby 1.8 on Feisty Fawn

Hi
I need to install Ruby. I looked up:http://packages.ubuntu.com/cgi-bin//search_packages.pl?version=all&subword=1&exact=&arch=any&releases=all&case=insensitive&keywords=ruby&searchon=names
for Ruby
and I got the following results pulled up for me:

Package dpkg-ruby

# feisty (devel): ruby interface for dpkg [universe]
0.3.2: all

clicking on that takes me to another page: http://packages.ubuntu.com/feisty/devel/dpkg-ruby

Do I need to install the following suggested on this page:

#

libdpkg-ruby1.8
    modules/classes for dpkg on ruby 1.8

#

[dep] ruby1.8
    Interpreter of object-oriented scripting language Ruby 1.8

----------------

Thanks again.
