Freeradius 3.0.19 and 3.0.21 can not find proto_acc.so and proto_auth.so.

I had 3.0.19 before and now have installed 3.0.21.
But for both versions I got and get:

Loading library using linker search path(s)
Defaults         : /lib:/usr/lib

      port = 1812
   limit {
      max_connections = 16
      lifetime = 0
      idle_timeout = 30
   }
}

      idle_timeout = 30
   }
}

As I saw at freeradius site there are only 2 proto_ modules - proto_ and
proto_dhcp.
Is it normal and does not it affect anythingor not ?
Should I change my setting to avoid it or what is necessary to do ?
Or it does not affect to anything and should be forgotten.
