Angular Unknown Provider - $anchorScrollProvider

I'm probably missing something obvious here, but I'm out of ideas, so:

I have the following code:

app.run(function ($rootScope, $location, $anchorScroll, $stateParams, $timeout, $anchorScrollProvider) {
    $rootScope.$on('$stateChangeStart',
        function(newRoute, oldRoute) {
            $timeout(function () {
                    $anchorScrollProvider.disableAutoScrolling();
                    $location.hash($stateParams.scrollTo);
                    $anchorScroll();
                },
                100);
        });
});

I added the $anchorScrollProvider code today, and I'm getting the following error:

Error: [$injector:unpr] Unknown provider: anchorScrollProviderProvider <- anchorScrollProvider

Reading the documentation, it looks like $anchorScrollProvider is part of the base ng modules, which to me means the above should work, but why doesn't it?
