Problems with GNOME 1.4 installed from tarballs

["Chaosmage" <chaosmage newmail ru>]

Hello!
It was my first try of installing GNOME from tarballs, so I read all the
instructions on GNOME site as well as Gnome Installation Guide and followe
them accurately. All GNOME system apps compiled and installed succesfully
(there were problems with some additional apps but that's not the case).
After I rebooted my system and logged in to GNOME (using gdm) I saw only
blank desktop and could not do anything because my mouse clicks and keyboard
input did not produce any reaction. If someone encountered such a problem or
can guess anything about it please reply. I would appreciate any help.
