Subject: Re: How do I get irb to use readline, (with OS X)?

Sorry for being vague. What I want is simpler that that - I want to be able to
use the arrow keys (or even ^p) to go back through the history, and to move
back through a line and edit it!

I can't use any line editing keys right now, its getting irritating!

Completion, I think, allows TAB to complete  the names of methods, correct?

[ensemble] ~/p/ruby/vcard $ irb -r irb/completion
/usr/lib/ruby/1.6/irb/completion.rb:10:in `require': No such file to load -- readline (LoadError)
        from /usr/lib/ruby/1.6/irb/completion.rb:10
        from /usr/lib/ruby/1.6/irb/init.rb:197:in `require'
        from /usr/lib/ruby/1.6/irb/init.rb:197:in `load_modules'
        from /usr/lib/ruby/1.6/irb/init.rb:195:in `each'
        from /usr/lib/ruby/1.6/irb/init.rb:195:in `load_modules'
        from /usr/lib/ruby/1.6/irb.rb:52:in `start'
        from /usr/bin/irb:13

ext/readline is supposed to be part of ruby, isn't it?

I also can't see a /usr/lib/libreadline*, so I really think I'm missing something!

Cheers,
Sam
