BIOCGDLTLIST was added to /sys/net/bpf.h after 5.0 was released, which
means you'll have to install a new kernel and copy its includes ( cd
into /usr/src/include and run "make copies" ) before libpcap will

If you're planning on building more than just libpcap, you might want
to just make world instead of trying to figure out what needs to be
updated for each thing you build to work.
