RC3 Install problems

[Scott Horowitz]

I've never had a problem with Xfce until now. I'm using Benedikt's 
graphical installer and installing RC3 right over RC2 (as I've 
successfully done with each new version of Xfce), but when I tried 
restarting X, I hit some errors. I then tried renaming the ~/.config 
directory in case that was causing problems, but that didn't help. I 
finally just tried uninstalling Xfce and doing a clean install of RC3 
and have still encountered the same problem. This is what I currently get:

[stonecrest at x1-6-00-0b-cd-33-e7-2a ~]$ startxfce4
/usr/local/bin/startxfce4: X server already running on display :0.0
/usr/local/etc/xdg/xfce4/xinitrc: line 52: xscreensaver: command not found
Agent pid 11703
which: no dbus-launch in 
(/usr/local/bin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/usr/lib/jre/bin)
/usr/local/bin/xfce4-session: error while loading shared libraries: 
libxfsm-4.2.so.0: cannot open shared object file: No such file or directory
Agent pid 11703 killed

I installed all four .bin files (gtk, xfce, xfce-goodies, and terminal), 
what could be the problem? I'm running Fedora Core 3. Thanks for any help.
