Can you tell me where any of this is documented?
I can't find squat about gamin.
no man page and no docs in the /usr/local tree
Checked the port options for gamin itself and see there's a place to turn on the poller, to that should solve that problem.
But where does one learn about disabling specific directories or other info?

Thanks,
