At least on FreeBSD 10 with gcc 4.6 as a ports compiler I need the following
patch to compile net/vde2:
--- src/vde_pcapplug.c.orig	2012-01-29 13:06:10.495087022 +0200

Explanation:
- without including net/bpf.h I get compiler errors for BIOCSHDRCMPLT,
BIOCIMMEDIATE and BIOCFEEDBACK
- we don't need sys/socket.h under VDE_FREEBSD, because it is already included
unconditionally earlier in the file
- pcap.h inclusion has to be after net/bpf.h, because otherwise pcap/bpf.h
redefines some definitions from net/bpf.h

P.S. my pcap.h comes from libpcap-1.2.1
