log_debug()

I simply installed the module, added a role reference to my Custom Content. Went to edit an existing node and got an error:

PHP Fatal error: Call to undefined function log_debug() in /var/www/{site}/sites/all/modules/rolereference/rolereference.module on line 933, referer: http://{site}/node/16670

Fixed by commenting the log_debug() line as follows:

/*
 * CCK field Token API hook_token_value implimentation
 * @see content.token.inc @ http://drupal.org/node/156860
 *
 * @param String type Type of value to process
 * @param Array object Field values
 * @param Array options Options array
 * @return Array An array of token-name => String value
 */
function rolereference_token_values($type, $object = NULL, $options = array()) {
  if ($type == 'field') {
    $item = $object[0];
    $tokens['rid'] = $item['rid'];
    $tokens['role'] = $item['view'];

    $all = array();
    foreach ( $object as $item ) {
      $all['rid-all'][] = $item['rid'];
      $all['role-all'][] = $item['view'];
    }
    foreach ( $all as $key => $values ) {
      $tokens[$key] = theme('rolereference_tokens_all', $values, $key);
    }
    // log_debug('tokens=' .print_r($tokens, true));
    return $tokens;
  }
