Download the package from http://www.realvnc.com/cgi-bin/download.cgi

Go to root user.

yum -y remove vnc vnc-server
yum -y install compat-libstdc++-296
cd <your downloaded package path>
rpm -ihv vnc-4_1_2-x86_linux.rpm
cd /usr/lib/xorg/modules/extensions/
ln -s /usr/X11R6/lib/modules/extensions/vnc.so libvnc.so

NOTES:
   1) Only tested under FC5 (FC5 changes some X's paths).
   2) Anybody with more knowledge, please, add the step for add the 
gnome menu option!!!!!.

Regards

1 hour ago, I was working with a remote machine using VNC, I updated VNC 
on that machine because new version fix a security issue.

I updated the remote server and the remote cliente (using yum)

[server@cura gdm]# yum list installed | grep vnc
vnc.i386                                 4.1.1-37.fc5           installed
vnc-server.i386                          4.1.1-37.fc5           installed

[client@sdg01 ~]# yum list installed | grep vnc
vnc.i386                                 4.1.1-37.fc5           installed
vnc-server.i386                          4.1.1-37.fc5           installed

But now, I can't use VNC to access the GUI in the vncserver.
In server side, I can see in /var/log/gdm/:0.log messages as:

I use vnc into X, as this:
