Does anyone know how to get readline support working for an Intel  
10.4.5?

This package doesn’t work.

Readline library is already there. (It’s not GNU’s, I think it’s  
NetBSD’s.)

Tiger’s default ruby installation doesn’t use it however. If you  
compile ruby 1.8.4 from the source, irb will have readline support  
enabled automatically.

Yes, you are right.

head /usr/include/readline/readline.h  
/\* $NetBSD: readline.h,v 1.11 2004/01/17 17:57:40 christos Exp $

However it’s not perfectly gnu-compatible. I haven’t tried with ruby (I  
installed readline 5 from sources), but with GiNaC interpreter it does  
not compile.
