rubycas-server 國際化出現問題，<span style="color: red">[label.central_login_title]</span>
修改如下文件即可：/program/ruby/lib/ruby/gems/1.8/gems/rubycas-server-1.1.1/lib/casserver/localization.rb
將：
set :translations, File.dirname(__FILE__) + "/../../locales"
替換爲：
#set :translations, File.dirname(__FILE__) + "/../../locales"
R18n.default_places { File.dirname(__FILE__) + "/../../locales" }
