irb cursor navigation

Whenever I use irb on my OS X 10.4 box, pressing left, right, up, or down
results in ^[[D, ^[[A, etc instead of the intended effect. Is there a fix?

Thank you,

~Matthew Maycock

Great, I have the same problem. Was just gonna ask myself. I have it on
RedHat Linux 7.3.

It's most likely a lack of the readline library being installed. If you're
using the built in OSX ruby install it's recommended that you build your
own. Search this list for a LOT more information regarding ruby and
readline.

I don't have this problem on my OS X 10.4 box. I compiled and
installed my own copy of Ruby following these instructions >>

Make sure you read the part about /usr/local linked on that page.

On OS X 10.4, you are running into Apple's long standing readline
problems. There is a step-by-step fix described here:

However, there are other problems with Apple's ruby, so you may
seriously consider compiling your own.
