Thanks for the link.  I'm trying to get tab completion going on Mac OS 
X, from the suggested:

% irb --readline -r irb/completion
/usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require': No such file 
to load -- readline (LoadError)
         from /usr/local/lib/ruby/1.8/irb/completion.rb:10
         from /usr/local/lib/ruby/1.8/irb/init.rb:218:in `require'
         from /usr/local/lib/ruby/1.8/irb/init.rb:218:in `load_modules'
         from /usr/local/lib/ruby/1.8/irb/init.rb:216:in `each'
         from /usr/local/lib/ruby/1.8/irb/init.rb:216:in `load_modules'
         from /usr/local/lib/ruby/1.8/irb/init.rb:21:in `setup'
         from /usr/local/lib/ruby/1.8/irb.rb:54:in `start'
         from /usr/local/bin/irb:13

But as you can see, I'm getting errors.  Any ideas?
