What Does Gnome-looks.org Look for to Find Gnome?

[Stephen Morris]

Hi,

Does anyone know what Gnome-looks.org looks for the determine that 
Gnome is installed? When I go to Gnome-looks.org it tells me it cannot 
find Gnome on my system therefore not all of its functionality will 
work. Is there something that I need installed for Gnome the would 
enable Gnome-looks.org to know that Gnome is installed and when I am 
accessing the site I'm accessing it from Gnome?

regards,

Steve
