Anyone could help with this issue?

There is an issue for the Support file cache related to the Zen theme here: http://drupal.org/node/234313. It seems that because the Zen theme doesn't have the _phptemplate_page function in the template.php, this might be happening. I found the _phptemplate_page function in the template-subtheme.php file. I tried adding the command they suggested right under it, but I would get errors like: Fatal error: Call to undefined function sf_cache_dispatch(). Can anyone please help solve this issue? I'd really like to have bundles of CSS and JS files for only tha pages I need.
