I want to use the library ‘rubyful\_soup’  
([Rubyful Soup: "The brush has got entangled in it!"](http://www.crummy.com/software/RubyfulSoup/))

Using ‘gem install rubyful\_soup’ command, I installed the library.  
The library is installed at /var/lib/gems/1.8/gems/.  
When I use the library with irb, I typed

_require ‘rubyful\_soup.rb’,_

but got an error message that ruby could not find such a file  
‘rubyful\_soup.rb’.  
So after googling, I found the solution. The solution was to insert the  
statement

require ‘rubygems’

before the statement

require ‘rubyful\_soup.rb’.

It works well with irb, but I get an error message when practically  
using with a controller class in a rails application.

Please help =)
