[Rails] rubyful_soup works fine as an RB file but bugs in Rails

This is the code:

1  require ''rubyful_soup''
2  require ''open-uri''
3
4  url = "http://www.google.com/search?q=ruby"
5  open(url) {
6    |page| page_content = page.read()
7    soup = BeautifulSoup.new(page_content)
8    result = soup.find_all(''a'', :attrs =>
{''class'' => ''l''})
9    result.each { |tag| puts tag[''href''] }
10 }

it works fine when i ran it: ruby rfs.rb
but when i wrap it with <%%> and try launching it in Rails, the 
following occours:

 TypeError in Articles#meca

Showing app/views/articles/meca.rhtml where line #2 raised:

superclass mismatch for class StackingParser

Extracted source (around line #2):

1: <%
2:   require ''rubyful_soup''
3:   require ''open-uri''
4:
5:   url = "http://www.google.com/search?q=ruby"

[Rails] Re: rubyful_soup works fine as an RB file but bugs in Rails

Okay,

it was beacuse Mechanize (already installed) and Rubyful_soup both use
the StackingParser name for their classes (probably include some mutual
library for parsing). The simple short-term way to solve this enigma is
by ''gem uninstall mechanize''.

;-)
