Hi,
There are already working spec files and pre-built RPM's for Fedora, RHEL, and CentOS that are actively maintained. See: http://wiki.freeradius.org/Red_Hat_FAQ
personally, I handroll mine from the source because then i choose what goes in and what doesnt (and often require all the debugging features on etc). however, I have used these RPMs supplied for CentOS and Fedora in certain 3rd party occasions and they work exactly as advertised (bringing back that nostalgia of installing 1.0.x onto a redhat box the first time around :-) ) I'd _prefer_ to run from yum/apt/yast but recently a lot of programs have required me to be running bleeding edge to get the features needed now.. this does sometimes happen with technology drives and i know that eventually i can just use the OS supplied version again when they've caught up :-) alan
