Where did you find that module?  It's obviously not up-to-date, but it
may work after some modifications...

The udp module is obsolete, and gen_udp does not have a start
function.  Just remove this call.

The problem here is that the snmp_mgr module is using port 4000 by
default, for some historic reason.  Use the option {agent_port, 161}
to snmp_mgr:start().
