Net_SNMP_util is a wrapper around Net::SNMP, which provides snmp v3 support,
but requires binaries.  Snmp_util.pm doesn't support snmp v3, but does
support snmp v2 with a perl-only implementation.  So, for deployments on
windows or when snmp v3 is not used, Snmp_util.pm is the superior product,
and whenever snmp v3 is used Net_SNMP_util is the required product.
