Installing Phalcon on OSX

I did everything described here (for OS X) and

I also added to the php.ini and restarted the webserver. I copied the compiled lib to /Applications/XAMPP/xamppfiles/lib/php/extensions

But when I search for "phalcon" in phpinfo there is no entry, so phalocn was not installed. Has anyone an idea what I can do to fix this problem?

PS: I use xampp as web server (PHP Version 5.5).

brew install is not the XAMMP one, brew install should avoid the need to use Xammp that create a separate env...follow any tutoriel that guide you installing php and related natively then add the extension as explained...
