Can't use ruby-rtf gem

I’m new to ruby, rails, and gems, and trying to add an feature to a
RoR’s app so users can export a file, and then edit it using
Microsoft’s Word. (This is an app where telling folks to use
OpenOffice or some other editor isn’t really an option). So I
researched a little and think that using ruby-rtf to create rtf files
is the best way to go. However, I can not use this gem; and I’m not
sure if I did not install it properly or what.

I downloaded the rtf-0.1.0.gem file and ran “gem install rtf-0.1.0”
and now if I do a “gem list” I see it in the list. So I create a file
called rtf.rb which contains this:
require ‘rubygems’
require ‘rtf’
include RTF
document =, ‘Times New Roman’))
document.paragraph << “This is a short paragraph of text.”‘my_document.rtf’) {|file| file.write(document.to_rtf)}
and then run it with “ruby rtf.rb”, and get this:
./rtf.rb:3: uninitialized constant RTF (NameError)
from C:/ror/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/
custom_require.rb:27:in gem_original_require' from C:/ror/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:inrequire’
from rtf.rb:2
This is all happening on a Windows PC.

Can someone tell me what I’ve done wrong?
