The ports are defined during installation.  Before running the install, 
you can set the SGE_QMASTER_PORT and/or SGE_EXECD_PORT to force the 
installer to use those port numbers.  Otherwise it will take the port 
numbers defined in /etc/services, or it will ask you for port numbers if 
none are defined in /etc/services.
