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
