Fatal Error Call to Undefined Function

I have the gallery app installed, and when I add the function:

 <?php perch_gallery_albums(); ?>

to a page I get the error "Fatal Error Call to undefined function" on whatever line I put it on. I was not getting this error in the previous version of perch runway, and I am sure that I am running the latest versions of both Perch and the Gallery app.

I have included the runtime at the top of the page like so.

<?php include('perch/runtime.php'); ?>

Here is my diagnostics report as well
