Installing PHP PEAR PECL and DRUSH extensions on MAMP for Mac OS X 10.7 +

drush MAMP PRO

// We we need to add PHP's binaries to our path. The path is an environment variable that denotes which directories to look for commands in. The path can be modified by editing the ".profile" file under your home directory. I've used version 5.3.20 of PHP, but you can choose from whichever versions are available to you.

  $ echo "export PATH=/Applications/MAMP/bin/php/php5.3.20/bin:$PATH" >> ~/.profile

//Now you can either restart your terminal session or run the following from your home directory to read in the new path variable.

  $ . ./.profile

//You should now have the correct binaries on your path and can check this by running the "which" command again.

  $ which php
  /Applications/MAMP/bin/php/php5.3.20/bin/php

  $ which pear
  /Applications/MAMP/bin/php/php5.3.20/bin/pear

  $ which pecl
  /Applications/MAMP/bin/php/php5.3.20/bin/pecl
