installing gnome 2.4 as 'its own gnome'

Hello all, Now that Gnome 2.4 is out (http://www.gnome.org/start/2.4/) my questions is ... How does one go about downloading and installing this as its own Gnome on SuSE 8.2 (ie... I would like to have the option of either using the gnome I am using now, or logging in and using gnome2.4)?
