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::Pie.new

graph.add :pie, ‘’, {  
‘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.rb:134:in`activate’ from c:/ruby/lib/ruby/site\_ruby/1.8/rubygems.rb:49:in `gem' from c:/ruby/lib/ruby/gems/1.8/gems/scruffy-0.2.5/lib/scruffy.rb:18 from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in`ge m\_original\_require’ 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,  
Andrés

gem install builder

for some reason it wasn’t included as a dependency in the .gemspec

Thanks Michael, I didn’t know that “builder” was a gem. Now the error  
has changed: I’ve to install RMagick 😃
