Custom User Profile Does not work in new theme

Hello
I am porting to a new theme and my custom user profile does not work. In my old theme I did not have a template.php file so as per the instructions here: http://drupal.org/node/35728 I aded the following code to a new template.php file:

<?php
/**
* Catch the theme_user_profile function, and redirect through the template api
*/
function phptemplate_user_profile($user, $fields = array()) {
  // Pass to phptemplate, including translating the parameters to an associative array. The element names are the names that the variables
  // will be assigned within your template.
  /* potential need for other code to extract field info */
return _phptemplate_callback('user_profile', array('user' => $user, 'fields' => $fields));
  }
?>

However my new theme (Barroness) does have a template.php file, so I added the above code to it and am running into problems. No matter where I seem to put thr code it screws up the layout and throws the sidebar beneath the content. Can anyon help? The contents of the existing template.php are below:

<?php
// $Id: template.php,v 1.1.2.2 2007/04/10 00:28:25 jwolf Exp $

// regions for barron 
function barron_regions() {
    return array(
        'sidebar_left' => t('sidebar'),
        'content_top' => t('content top'),
        'content_bottom' => t('content bottom'),
        'footer' => t('footer')
    );
}

// sets delimiter and styles for $links
function phptemplate_links($links, $attributes = array('class' => 'links')) {
  $output = '';

  if (count($links) > 0) {

    $num_links = count($links);
    $i = 1;

    foreach ($links as $key => $link) {
      $class = '';

      // Automatically add a class to each link and also to each LI
      if (isset($link['attributes']) && isset($link['attributes']['class'])) {
        $link['attributes']['class'] .= ' ' . $key;
        $class = $key;
      }
      else {
        $link['attributes']['class'] = $key;
        $class = $key;
      }

      // Add first and last classes to the list of links to help out themers.
      $extra_class = '';
      if ($i == 1) {
        $extra_class .= 'first ';
      } else {
        $output .= '&nbsp;&bull; &nbsp;';
      }
      if ($i == $num_links) {
        $extra_class .= 'last ';
      }
      $output .= '<span class="'. $extra_class . $class .'">';

      // Is the title HTML?
      $html = isset($link['html']) && $link['html'];

      // Initialize fragment and query variables.
      $link['query'] = isset($link['query']) ? $link['query'] : NULL;
      $link['fragment'] = isset($link['fragment']) ? $link['fragment'] : NULL;

      if (isset($link['href'])) {
        $output .= l($link['title'], $link['href'], $link['attributes'], $link['query'], $link['fragment'], FALSE, $html);
      }
      else if ($link['title']) {
        //Some links are actually not links, but we wrap these in <span> for adding title and class attributes
        if (!$html) {
          $link['title'] = check_plain($link['title']);
        }
        $output .= '<span'. drupal_attributes($link['attributes']) .'>'. $link['title'] .'</span>';
      }

      $i++;
      $output .= "</span>\n";
    }

  }
  return $output;  
}
