whois.cart installation

Another thing (per haps I should create a new ticket) I am trying to install whois.cart from whoiscart.net
I get an error during install:
during install I enter all credentials for the database and when hit next I get a screen with, "Cannot run without designated path!!! Exiting."

and through their support ticket I got this:
"This occurs if your PHP setup doesn't give the system a proper SCRIPT_FILENAME or PATH_TRANSLATED value in the $_SERVER array."

Do you know what it is they are saying?
Is the (encoded) script looking for /var/www/html while the domain is at /home/domain/public_html ?
I suspect this, but I am afraid to change it and break VM (if I knew where to look for it , that is)

They give support on their script but not on server settings. According to their requirements the server is good to go with PHP 5.1.6, Apache 2.2.3, centos 5.1

My suspiscion is that VM needs /home for the domains while default is /var/www/
