Problems importing facebook client library

[eluser]igniteflow[/eluser]
Solved it, by putting

Code:

/*
| -------------------------------------------------------------------
|  Native Auto-load
| -------------------------------------------------------------------
|
| Nothing to do with config/autoload.php, this allows PHP autoload to work
| for controller types and some third-party libraries.
|
*/
function __autoload($class)
{
    if(strpos($class, 'CI_') !== 0)
    {
        $class = APPPATH . 'classes/'. $class . EXT;
        $lib = APPPATH . 'libraries/'. $class . EXT;

        if(file_exists($class))
        {
            include_once( $class );
        }

        else if(file_exists($lib))
        {
            include_once( $lib );
        }
    }
}

in config.php. I doubt this is the most efficient way of including a class in CI though, and would like to hear the best way to do it...
