Problems with "scruffy"

[Andrés Suárez]

Hi,

I've the last one-click installer and the scruffy gem. And if I try to
run this example script:

require 'rubygems'
require 'scruffy'

graph = Scruffy::Graph.new
graph.title = "Favourite Snacks"
graph.renderer = Scruffy::Renderers:ie.new

graph.add ie, '', {
'Apple' => 20,
'Banana' => 100,
'Orange' => 70,
'Taco' => 30
}

graph.render :to => "pie_test.svg"
graph.render :width => 300, :height => 200,
:to => "pie_test.png", :as => 'png'
-------------------

but I've obtained the next error:

c:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:578:in
`report_activate_error': Could
not find RubyGem builder (>= 2.0) (Gem::LoadError)

from
c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in `re
quire'
from scruffy_petete.rb:2
shell returned 1
------------

Where is the problem?

Regards,

Thanks Michael, I didn't know that "builder" was a gem. Now the error
has changed: I've to install RMagick
