Bingo. That's it. I have ruby 1.8.7 installed, and recently installed 
1.9 as well. It never occurred to me that Rubygems was catching both 
installs, and that is clearly the case. Hadn't used the 'gem list -d {}' 
command until I read your email. Problem explained, if not solved. 
Interesting....

A day full of bright spots of all sorts!
