description:
Zabbix_agentd is a threaded program, and it tries to muck with the
global `_res' variable.  That's not supported on NetBSD, and IME
causes the zabbix agent daemon to exit shortly after having been started.
Convert to instead using res_ninit(), res_nsend(), and res_nclose().
Bump PKGREVISION.
