any ideas on how to get readline support in OS X 10.3?

[Sam Roberts]

I just got this working for ruby1.8 on OS X 10.2... then upgraded.

The old hack involved installing the headers for a library that was
actually there, but with 10.3 and recent devel tools the headers ARE
there, but I still can't get it working.

Any ideas, this is quite painful!

I'm building 1.8 from cvs, heres the problem:
