PHP中pear的安装问题，无法调用mail.php？

安装教程：http://www.cnblogs.com/Excellent/archive/2011/11/22/2258304.html
当使用后面的测试代码是报错。Warning: require_once(Mail.php) [function.require-once]: failed to open stream: No such file or directory in C:\wamp\phpDemo\index.php on line 2

Fatal error: require_once() [function.require]: Failed opening required 'Mail.php' (include_path='.;C:\php5\pear') in C:\wamp\phpDemo\index.php on line 2
而查看phpinfo时发现"include_path .;C:\php5\pear" 而我的include_path中已经改了。求大神解答。

教程的方法是对的，但是不能完全照它操作，可能是PEAR版本升级了，我安装后也是没有Mail这个包的，如下

E:\wamp\bin\php\php5.5.12>pear list
