The install completed without errors, but running sudo ./freeradius -X produces the following:

ps aux | grep free


ps ax | grep radius

check for the process already running. 

kill -9 PID

then start radius in debug mode.
/usr/sbin/freeradius -X

you probably have one started manually and one from init.d, and they are arguing over port access.
