Hi, I cannot get the gnome working by following the steps written in wiki/GNOME

To debug the problem I ran the commands which written in
~/.xinitrc.d/90-gnome.sh line by line in the xterm.

sudo launchctl load -w /Library/LaunchDaemons/org.freedesktop.dbus-system.plist
launchctl load -w /Library/LaunchAgents/org.freedesktop.dbus-session.plist

prompt> metacity
Window manager warning: Locale not understood by C library,
internationalization will not work

        Using the fallback 'C' locale.
Xlib:  extension "RANDR" missing on display ":0.0".

prompt> quartz-wm
