      Run the asset precompilation rake task. You can specify the full path \
      to the rake executable by setting the rake variable. You can also \
      specify additional environment variables to pass to rake via the \
      asset_env variable. The defaults are:

        set :rake,      "rake"
        set :rails_env, "production"
        set :asset_env, "RAILS_GROUPS=assets"
        set :assets_dependencies, fetch(:assets_dependencies) + %w(config/locales/js)
    DESC
    task :precompile, :roles => :web, :except => { :no_release => true } do
      from = source.next_revision(current_revision)
      if capture("cd #{latest_release} && #{source.local.log(from)} #{assets_dependencies.join ' '} | wc -l").to_i > 0
        run %Q{cd #{latest_release} && #{rake} RAILS_ENV=#{rails_env} #{asset_env} assets:precompile}
      else
        logger.info "Skipping asset pre-compilation because there were no asset changes"
      end
    end

  end
end

I've tested the gem. It works like a charm. GREAT WORK !!!

turbo-sprockets-rails3 is working great for me. Thanks!
