Error on install - new HostGator account

I have created a new hosting account at HostGator, created an empty database, uploaded the wpmu files and begun the install process. I immediately get the following error. HostGator tech support informs me that this is an error with the script. Any advice on how I can correct this error.

Fatal error: Call to undefined function wp_die() in /home/kirkward/public_html/wp-includes/wp-db.php on line 1147
