user/group and permissions CentOS 4.4

In process of building 1.4 on CentOS 4.4. When started (as root) in debug mode, all goes well. When using default user/group nobody I get

Info: Starting - reading configuration files ... radiusd: Couldn't open /usr/local/var/log/radius/radius.log for logging: Permission denied (rlm_exec: Wait=yes but no output defined. Did you mean output=none?) radiusd: Couldn't open /usr/local/var/log/radius/radius.log for logging: Permission denied (Failed creating PID file /usr/local/var/run/radiusd/radiusd.pid: Permission denied)

Can someone give me a little guidance with the permissions and user/group setup for Cent. --Andrew Long
