Thread:Project:Support desk/PHP error in mediawiki setup

I am trying to setup mediawiki in a mac.

When I click on the setup mediawiki link, it reports this error - "PHP 5.3.1 is not compatible with MediaWiki due to a bug involving reference parameters to __call. Upgrade to PHP 5.3.2 or higher, or downgrade to PHP 5.3.0 to fix this. ABORTING (see http://bugs.php.net/bug.php?id=50394 for details)"

When I type php -v, I get this "PHP 5.3.4 (cli) (built: Dec 15 2010 12:15:07) Copyright (c) 1997-2010 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies"

I don't understand why the mediawiki setup thinks that I have php 5.3.1. installed. Any help to fix the problem would be appreciated...
