problem in adding disman-ping-mib

hi,

I want to add disman-ping-mib in net-snmp 5.2 package, its code is
there in with agent(netsnmp/agent/disman/ping) directory but it is not
build with package.

I made changes in agent makefile to add ping-mib as it is doing for
other mib like if-mib and i got my new snmpd agent, but when I am
Quering for ping-mib from mager command (like snmpwalk,
snmoset,snmpget) it is not responding.

1. Can anyone tell me what changes exactly i need to do for adding
disman-ping-mib in net-snmpd agent ?

2. Is there any configuration changes requires on mager side for
quering to ping-mib(I am using MGSOFT browser which has disman-ping-
mib in its MIB tree) ?

3. Can i get release of net-snmp package build with disman-ping-mib ?

Thanks,
Aleem
