Well I was able to have my cake and eat it too.  I got command-line history edit to work by installing Term::Readline.  No need for

Installing pm_termradlineg breaks cpan, because it will quickly exit with a message that it has run out of memory.  This is on a system with 32G and the histfile was short, so the problem is elsewhere.  I think someone else complained about it too.  <div>
