OK. Well, I've discovered that this script actually runs just fine in 
the command shell. But, it doesn't run inside my Ruby editor. I get the 
"nil" error when I run the script inside my Ruby editor.  But, if I go 
to the command shell with a PDF file in that directory and run the 
script, it runs fine. So, I've sent an e-mail to my Ruby editor folks. 
Thanks.
