You have to compile in the 'readline' module. In Python 2.0 that means
editing 'Modules/Setup' and uncommenting the line that mentions readline.
You'll probably also want to uncomment some other lines.

If that doesn't work, you might lack the headerfiles for readline, or they
might be in an odd location. If you don't have them installed, you have to
find an RPM that provides them (probably readline-devel.<something>.rpm.) If
they are in an odd location, you have to tweak the -I and -L arguments
behind readline. 

This will almost all be unnecessary in Python 2.1, where the modules are
autodetected using Python's distutils. It's less easy to supply your own
location, but it will hardly be necessary, in most cases. In Python 2.1, a
single 'make' after 'configure' will build everything for you :)
