and 'radiusd -X'  works? if so, what about 'radiusd -x'

sounds very much like the server is unable to write its
logging files - those directories must be writable by
the radiusd process owner (usually radiusd or nobody).
if you've installed as root or run things as root you
may find these permissions incorrect. another issue
is the run PID file - often the location is also wrong 
permission - eg /var/run/radius/radiusd.pid
