Hi,

I can't think what might be causing this for you... Do you have other 
pcap libraries installed on the system? Perhaps a define is incorrect.

Are you trying this on a 7.2 or a HEAD system? I believe 7.2, so that 
should rule out changes in HEAD.

Do you have BPF headers present on the system? Have you checked the 
output of config.log? Do you have a bpf device in your kernel?
 -- I think that might be it. The fix might be to specify 
--with-pcap=bpf in CONFIGURE_ARGS in the port.

I just built the port on an i386 system tracking RELENG_7 sources, and 
couldn't reproduce this problem, although I have bpf in kernel there.

thanks,
BMS
