gnome fails to start after upgrade

[andy at neu.net]

I just finsihed running the 2.12 upgrade script on 6.0 release, it
reported that it
finished sucessfully.  However, after a reboot Gnome will not start.  I
had gnome_enable in rc.conf, and when it boots I get the following error
on the console:
Nov  7 16:05:47 alum gdm[668]: failsafe dialog failed (inhibitions: 0 1)
Nov  7 16:05:47 alum gdm[668]: failsafe dialog failed (inhibitions: 1 1)

If I issue  /usr/X11R6/bin/gnome-session from a prompt I get:
(gnome-session:1035): Gtk-WARNING **: cannot open display:

So, I removed gdm_enable from rc.conf.  I am able to get into an xwindow
environment by typing startx. Then when I am in xwindows if I issue
/usr/X11R6/bin/gnome-session, Gnome will open in many different xwindows.

 The following is from .xsession-errors:

Is there any more info that would be helpful in debugging this problem?
What else should I do to troubleshoot this issue?
Any and all help is appreciated.
