我正在尝试让我的本地Mac机器使用5.5版本的PHP。我已经运行了命令：
curl -s http://php-osx.liip.ch/install.sh | bash -s 5.5
并获得输出：
****

Get packager.tgz
Unpack packager.tgz

我在httpd.conf文件（LoadModule php5_module libexec/apache2/libphp5.so）的根目录中删除了对PHP行的注释，但是，当我返回到我的控制台并键入php -v时，我得到：
*******:~ ************$ php -v

仍然使用PHP版本5.4。我该怎么做才能让系统使用PHP 5.5？谢谢！
