I haven't kept up on the snmp_utils development, but last I checked it
did not know how to parse certain snmp v2 features and would die.

This does not forbid mrtg from using snmp v2, only from parsing mibs
written in the V2 format.

No, it is related to the options[]: statement.  You need to add "guage"
for items that go up and down on their own (as opposed to monotonically
increasing counters)
