There's something screwy about your readline installation (or, if you
didn't install GNU readline, about the libedit that OS X supplies).
This is kind of par for the course on OS X, of course.

I can never remember how Darwin kernel versions map to OS X versions?
But the real question is whether you've got (any vestiges of) a manual
readline installation.
