Xdebug bad Zend API Version Number

I am having trouble upgrading xdebug for MAMP. I was running version 2.2.0 and there was a known issue that I ran into: PhpStorm
and Xdebug not breaking in Symfony2 Controller

I tried to upgrade to version 2.2.3 by following the instructions from http://xdebug.org/wizard.php

After downloading and extracting the xdebug tar I ran /Applications/MAMP/bin/php/php5.4.4/bin/phpize

Here is the output:

Configuring for:
PHP Api Version:         20100412
Zend Module Api No:      20100525
Zend Extension Api No:   220100525

I then copied the modules/xdebug.so file into the mamp php5.4.4 extensions dir: `/Applications/MAMP/bin/php/php5.4.4/lib/php/extensions/no-debug-non-zts-20100525/xdebug.

If I run /Applications/MAMP/bin/php/php5.4.4/bin/php
-v I get the following:

Xdebug requires Zend Engine API version 220090626.
The Zend Engine API version 220100525 which is installed, is newer.
Contact Derick Rethans at http://xdebug.org/docs/faq#api for a later version of Xdebug.

PHP 5.4.4 (cli) (built: Jul  4 2012 17:28:56)
Copyright (c) 1997-2012 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies

I have restarted MAMP and Apache and tried loading a page with phpinfo() and
I do not see Xdebug listed. If I moved the old xdebug.so file back in place the error is removed and phpinfo() show
xdebug as enabled

I managed to solve this issue by running /Applications/MAMP/bin/php/php5.4.4/bin/pecl install xdebug At first I was seeing issues with the Zend API number using pecl. I followed this post: pecl installs for previous php version and set the following: sudo /Applications/MAMP/bin/php/php5.4.4/bin/pear config-set php_ini /Applications/MAMP/bin/php/php5.4.4/conf/php.ini sudo /Applications/MAMP/bin/php/php5.4.4/bin/pecl config-set bin_dir /Applications/MAMP/bin/php/php5.4.4/bin/ Not sure if these configs had something to do with it failing before
