I know! The problem is that UDP is actually UDP encapsulation of PGM 
reliable multicast protocol. So to have it available you have to specify 
--with-pgm when doing configure.

One more comment: Latency tests use request/reply sockets which, quite 
naturally, don't work over multicast. So you'll end up with error 
anyway. The throughput tests should work though.
