Thanks for looking into this.  I'll keep testing and see if I can
isolate the
problem.

By the way, the reason that I didn't need "require 'rubygems'"  is because
I have the RUBYOPT environment variable set to "rubygems".  If I unset
this variable and do a "require 'rubygems'" before the "require_gem 'rio'" 
command, I get the same error.

Also, in case this might shed some light on my problem ...

  % ruby --version
  ruby 1.8.2 (2004-12-25) [i686-linux]
  % gem --version
  0.8.11

Prior to this, I had earlier problems with gems, and so I completely
uninstalled ruby (I had been using the 1.9.x version from cvs), and I 
re-installed it from the official 1.8.2 version, totally from scratch with 
none of my old libraries, scripts, or gems present on my system.  It
was only then that I installed "gem", and then "rio".

Thanks again for any help you folks might be able to give me on this.
