PHP CLI version issue

I am trying to use Zend Tool on my media temple Grid Server a开发者_开发技巧ccount. The problem is that the installed CLI version of PHP is 4.4.8 and Zend Framework needs PHP5. On an account basis its possible to choose PHP 4 or 5 but not so for CLI. Its possible to globally select to use PHP5 by using the extension .php5 but in the case of Zend Tool which is called by a shell script zf.sh i'm not sure what options i have. PHP5 is on the server at /usr/bin/php5 and someone at MT has suggested creating an alias so php=/usr/bin/php5 but i'm not sure that will work. Any ideas?

In zf.sh update the PHP_BIN line to:

PHP_BIN=/usr/bin/php5
