I've committed this to the port, however, did not bump PORTREVISION.
I have a couple other open PRs that will most likely result in
additional patch changes and I do not want to force people to update
over and over if I can avoid it.
To get the fix into your systems, simply update your ports tree and then
rebuild/reinstall net-snmp.
