"WWW::" を取っただけ。
grep すると他にも見つかる。必要ならここらへんも直すと良いかも:
./legacy_plugins/Filter/Translations/yahoo.rb: agent = WWW::Mechanize.new ./legacy_plugins/Download/nicovideo.rb: agent = WWW::Mechanize.new ./legacy_plugins/Publish/hatena_diary_writer.rb: @agent = WWW::Mechanize.new ./legacy_plugins/Publish/delicious.rb: @agent = WWW::Mechanize.new ./legacy_plugins/Publish/scuttle.rb: @agent = WWW::Mechanize.new ./legacy_plugins/Publish/mixi_diary_writer.rb: @agent = WWW::Mechanize.new ./lib-plugins/yapra/plugin/publish/mail.rb: attachments << file if file.kind_of?(WWW::Mechanize::File) ./lib-plugins/yapra/plugin/publish/mail.rb: attachments << file if file.kind_of?(WWW::Mechanize::File)
