Drush not seeing right CLI PHP version I am not able to get Drush to recognize the installed PHP 5.4.20 (cli).

$ php -v
PHP 5.4.20 (cli) (built: Oct 10 2013 18:41:48) 

$ drush
Your command line PHP installation is too old. Drush requires at     [error]
least PHP 5.3.3.


I logged out and in. Any quick thoughts?
Have you just now updated your PHP than you may need to restart the apache and check if it works, and still if you get the above error than check Installing and Troubleshooting Drush.

One dirty hack of installing the drush is mentioned here: https://drupal.org/files/drush-document_env_var-1841324-25.patch. But I won't recommend you to use this as you are already having the PHP 5.4 and that hack for PHP version &lt; 5.3.3
