error when new user tries to create a profile

When a new user logs in and tries to create a new profile when they click on save this is the error it spits out.

Fatal error: Call to undefined function nodereference_content_is_empty() in /usr/local/www/asylumtest/sites/all/modules/cck/content.module on line 892

the following is on line 892 of content.module
if (!$function($item, $field)) {
$filtered[] = $item;

I am not a php developer I can only barely edit php so I am unsure what I need to do to resolve this error. I am not sure if it is related to content profile or to the core of CCK.
