Please don't change that API, it's better with the error buffer argument
( should pick up that change), and it's been that way in
NetBSD for years.

IIRC, NetBSD contains substantial patches to libpcap that developers
are not content to throw away, so please do the usual "import to vendor
branch, merge vendor changes with trunk" dance with libpcap 0.9.4.
I assume that is what you're doing, I just want to make sure.
