Apparently Not Working

I don't think this is working with 6.13, I've followed the README.txt to the letter. I have enabled the module and added the following function to a custom module, but no go.

/**
 * - positive: BPV_INCLUSIVE or BPV_EXCLUSIVE  
 * - pages: array of Drupal paths
 * - types: array of content types
 * - bool: general-purpose boolean
 *
 * A block matches if pages or types matches or the boolean is
 * true.  A block is shown if (exclude XOR match).
 * 
 * The key is the name of the block. The first argument to its array must either be BPV_INCLUSIVE or BPV_EXCLUSIVE;
 * BPV_INCLUSIVE only displays the block whenever it matches the second or third argument.
 * BPV_EXCLUSIVE always displays the block unless it matches the second or third argument.
 * The second argument is an array of paths like in block control, and the third argument is an array of content types to match. 
 * The fourth is a general purpose boolean. Put whatever php here you want, that returns a boolean.
 */

<?php
function HOOK_bpv_config($name) {
  $blocks = array(
    'user-2' => array(BPV_INCLUSIVE, array('<front>'), array('front'), NULL),
  );
  return $blocks[$name];
}

Am I missing something?
