This should install drush for you using the PEAR packages.

Next, see whether you are seeing the following error message when invoking drush (by typing the command "drush"):

The following restricted PHP modes have non-empty values:                [error]

P.S.: I got this working on my NixWinD Linux hosting account. But being quite generic, these steps should work fine for most other cPanel configurations. Let me know if you face any difficulty following these instructions on your account. I would be happy to help you out. :-)
