nmap: route_dst_generic: Failed to obtain system routes: getsysroutes_dnet: sysroutes_dnet_find_interfaces() failed

Running a simple "namp -sS" on the network or a dedicated IP, I get this error:

route_dst_generic: Failed to obtain system routes: getsysroutes_dnet:
sysroutes_dnet_find_interfaces() failed

System is FreeBSD 11.0-CURRENT #1 r287321: Mon Aug 31 09:35:35 CEST 2015 amd64
and most recent port's security/nmap.

Any hints? I see this problem on several CURRENT systems.

regards,
Oliver
