There are some known problems for "make build":

To bootstrap (f)lex copy inetscan.c to scan.c.
Install lib/libcurses/curses.h before compiling lib/libterm.
Copy or link termcap.src into termcap for cap_mkdb
(or update share/termcap/Makefile).

This version uses the last neighbor discovery specs but:
 - some features in the kernel must be fixed (NA source
address and sockaddr_in6 structure bad alignment in mbufs
from system calls)
 - addrconf and router discovery must be done by gated
(ie an user process) then there is no code for it in kernel.
