[erlang-questions] erl: "Can't set long node name!"

I was following an example and found that my configuration lacks the  
ability to "set long node name."  I checked the crash dump, and it  
wasn't informative to me.  I would attach it, but it's 180K, so I'll  
only do that if asked to.

So, any idea what I should change in my configuration?
