There were a couple problems:
1. readline-devel needed to be installed, from CD3 of the SuSE distribution.
2. I'm automounting my home directory, running ./configure and make as an 
ordinary user, and then running make install as root.  The make install fails 
since root doesn't have access to change ext/extmk.log.  So exit, chmod 777 
ext/extmk.log, then su and make install works.  

And now the up-arrow works in irb.
