tip was really helpfull...
I managed to install clearos community edition 6.2.0
then managed to install wget with
yum install wget
# download the install script
# make it executable
chmod 744 install_SARG.sh
# if you are interested in what it will do (you should be -
# it's your server that will be changed!) then study the
# script with an editor...
# now run it
