irb has to be installed. There are instructions in the FAQ. it goes
something like (sorry about the sgml):

<sect1>How can I use Ruby interactively?
<p>

You can try using <tt>irb</tt>. The following is paraphrased from Goto 
Kentaro (Gotoken), and originally appeared in ruby-talk:444.

<enum>
<item>Get the latest tarball of irb from
<url url="ftp://ftp.netlab.co.jp/pub/lang/ruby/contrib/"
name="the contrib directory"> in the Ruby archive.

<item>Extract the <tt>irb</tt> directory tree.

<item>Add the location of the <tt>irb/</tt> directory to the $RUBYLIB
environment variable

<item>Make a symbolic link from $RUBYLIB/irb/irb.rb to a file called
<tt>irb</tt> somewhere in your path.

<item><tt>chmod +x $RUBYLIB/irb/irb.rb</tt>

<item>Possibly use <tt>rehash</tt> to tell your login shell about the
new command.

<item>Type <tt>irb</tt>
</enum>

If the <tt>readline</tt> extension module works with your interpreter,
it makes <tt>irb</tt> a lot more fun to use.
