I'm using ccl/openmcl on Mac OS X. (latest versions of both). When the lisp prompt is displayed, using the cursor keys to navigate the current line results in escape codes, rather than movement, eg:

`Welcome to Clozure Common Lisp Version 1.2-r9226-RC1 (DarwinX8664)!  

? (^[[D`

Here I've pressed the `(` key, and then the `left cursor` key.

When I run ccl/openmcl on a Debian Etch box, the cursor behaves as expected, and moves the insert point one position left.

I guess this is some sort of terminal configuration option?
