I've just built both static and dynamic netbsd-6 vax releases without
x11 from the same source
- http://sync.absd.org/vax/6-vax-2014-04-19-static/
- http://sync.absd.org/vax/6-vax-2014-04-19/
in case someone would like to compare the relative speeds on a slow box...

It needed a small tweak to the set lists which is in current but not
pulled up into netbsd-6 yet -
http://mail-index.netbsd.org/source-changes/2014/04/20/msg054188.html
otherwise it was just a standard ./build.sh with the following in
/etc/mk.conf

.if ${MACHINE} == vax
NOPIC=  # no shared libraries
MKX11=no
.endif
