Somewhere in the back of my mind sits a recollection that there's a
version problem, that we require a newer readline than shipped in
RH5.2. In redhat 6.1 we have 2.2.1 and that works but I suspect 2.0
will not do the callback method we use in the console handler.

Also note that you need the readline-devel package as well as the
library itself.
