Subject: ...rubygems... in require: no such file to load

I have a script requiring rubygems, rio, and more, plus a module in a 
non-standard directory. It  works fine on my machine, but not on the 
machine of a friend. 

Here's the important part of my module
    require 'session'
    require 'rubygems'
    require 'term/ansicolor'

    class String
      include Term::ANSIColor
    end
    
    module TestMe
      def sys(command)
        ...
      end
    end # TestMe

It is stored in /home/local/ruby/testme.rb
And this is the calling script:

    #!/usr/bin/ruby
    puts 'LOAD_PATH:',$LOAD_PATH.join("\n")
    puts 'RUBYLIB:',ENV['RUBYLIB']
    puts 'RUBYOPT:',ENV['RUBYOPT']
    
    require 'rubygems'
    require 'rio'
    require 'testme'
    include TestMe
    sys('ls')
    
    puts rio('/etc/passwd').gets

On my machine it successfully says:

    tmp>testme
    LOAD_PATH:
    .
    /home/local/ruby
    /usr/local/lib/ruby/site_ruby/1.8
    /usr/local/lib/ruby/site_ruby/1.8/i686-linux
    /usr/local/lib/ruby/site_ruby
    /usr/local/lib/ruby/1.8
    /usr/local/lib/ruby/1.8/i686-linux
    .
    RUBYLIB:
    .:/home/local/ruby
    RUBYOPT:
    nil
    system call: ls successful
    root:x:0:0:root:/home/root:/bin/bash
    tmp>

But on the friend's machine (who stores the module in 
/home/rrt/local/lib/site_ruby/1.8):

    tmp>testme
    LOAD_PATH:
    /home/rrt/local/lib/site_ruby/1.8/i386-linux
    /home/rrt/local/lib/site_ruby/1.8
    /usr/local/lib/site_ruby/1.8
    /usr/local/lib/site_ruby/1.8/i386-linux
    /usr/local/lib/site_ruby
    /usr/lib/ruby/1.8
    /usr/lib/ruby/1.8/i386-linux
    .
    RUBYLIB:
    /home/rrt/local/lib/site_ruby/1.8/i386-linux:/home/rrt/local/lib/site_ruby/1.8
    RUBYOPT:
    nil
    /usr/lib/ruby/1.8/rubygems/custom_require.rb:26:in `require': No such file 
    to load -- testme (LoadError)
    from ./testme:8

What's wrong? Something with the rubygems installation?
