Hi  
If you have used this before, did you have problems with the following  
line?

require ‘diff/lcs’

For this line, I am getting this error:

c:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in  
`gem_original_require': no such file to load -- diff/lcs (LoadError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in`require’  
from text.rb:1
