Want to remove Gnome and start again ( off suse 7.1 )

["dids" <richard diddyland com>]

It seems ( unless Im wrong ) that most gnome progs expect gnome to be in
/usr/local instead of /opt/gnome

whatever, i would like to remove all the gnome stuff on my machine ie libs
etc and start again by hand.

Can someone give me some pointers about which directories i can remove

Ive already done the rpms etc

Id also like to know which environment vars Suse is setting up for me by
default and how to stop it. eg GNOME_DIR

thanks
