@Perry:
Of course you have to set up the routes:

With @bastianallgeier at https://github.com/getkirby/kirby/issues/93 :

Open your file site/config/config.php and add the following lines, if there are no routes.
If you find there one or some routes, only add the two nested array’s in front of your existing route(s).

/*
---------------------------------------
Setup Kirby Routes
---------------------------------------
*/
c::set('routes', array(
    /* https://github.com/getkirby/kirby/issues/93 */
    array(
        'pattern' => 'sitemap.xml',
        'action'  => function() {
            return site()->visit('sitemap');
        }
    ),
    array(
        'pattern' => 'sitemap',
        'action'  => function() {
            return go('sitemap.xml');
        }
    ),
));

=>

Good luck!
