(1) Are the trap packets arriving? Run Wireshark to look for them.

(2) You probably need to set up your TrapListener with a community 
string, and your trap sender to use that same community string (for SNMP 
v2c anyway).

The example in the source code at 
http://snmplib.rubyforge.org/svn/trunk/lib/snmp/manager.rb
suggests you need to add something like :Community=>"public"
