I had not copied the entire makefile which will create
a rpm.

No.

The sessions are:
At snmpd machine:
# ps -ef|grep snmp

However the snmptrap command at the snmpd
(fc6.mypc.com) still can send trap:
# snmptrap -v 3 -u test_MD5_AES -l authPriv -a MD5 -A
12345x AES -X 87654321 -e 0x800000000102030405060708

At the snmptrapd machine:
# snmptrapd -f -C -c /home/tcma/snmp/snmptrapd.conf
-Le
netsnmp_assert !"registration != duplicate" failed
agent_registry.c:535 netsnmp_subtree_load()
netsnmp_assert !"registration != duplicate" failed
