That probably means GNU readline is not installed on your system. It's a 
separate library from ruby, and the ext/readline stuff will not build 
without it. If you're installing RPMs, you need you make sure you 
install the devel RPM, as I remember. Or you can just build readline 
from source. You can get tarballs at your local GNU mirror.
