sudo yum install net-snmp net-snmp-utils

After that it will run out of the box with the command:

sudo snmptrapd -A -d -n -Lf trap.log

RPMFusion release for YUM.

For people who have used yum on Fedora, you must have seen that couple of packages that you require are on Livna and couple of them on DAG and some others on FreshRPMs and Dribble.
