undefined function location_views_proximity_get_reference_location()

The current Dev version does not have an implementation of this function. Either disable the Sorting or complete the conversion please. This error will render your site completely un-usable until you use phpMyAdmin to fix the DB manually. This is an extremely critical item, things like this are best disabled it until its finished :D

Fatal error: Call to undefined function location_views_proximity_get_reference_location() in location_handler_sort_location_distance.inc on line 120

To recreate it simply install from fresh drupal/location, create a simple view with a proximity filter and then try to add sorting. It no workie.
