I'm a bit late in updating this thread - but for the record, and
in case anyone else runs into this, the problem turned out to be
related to the NetBSD libpcap library.
When I built a local version of libpcap-0.8.3 and compiled pmacctd
against that, the core dumps stopped happening.
I have not fully deployed pmacctd yet but I tested out a few features
and there were no further problems on the NetBSD platform.
