Flickraw - I need help to install it

Hi all forum. Can I ask for your help to install Flickraw?

I was using it (v0-4-2) without any inconvenient but, a couple of weeks
ago I uninstalled it and I installed the last version and now I am
having errors (please see bellow) and I dont know why because I did not
change the code … I only applied an upgrade:

no such file to load – flickraw
RAILS_ROOT: …/config/…
gem_original_require' /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:inrequire’
require' /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.1/lib/active_support/dependencies.rb:342:innew_constants_in’
require' #{RAILS_ROOT}/app/controllers/frontpage_controller.rb:125:increate_subject_next’
This error occurred while loading the following files: flickraw

Thank you all for your help.
Best regards and keep in touch.
