AFAIK it's allowed to use "detached" licence. In this case, you must
include the copyright notices (acc. condition #3) and point to location
of the licence for every binary you use (to be on the safe side).

``2. Redistributions in binary form must reproduce the above copyright
     notice, this list of conditions and the following disclaimer in the
     documentation and/or other materials provided with the distribution.''

Please note the ``in the documentation and/or other materials provided
with the distribution'' phrase.


P.S. Very interesting, that binary NetBSD distribution seems doesn't
explicitly contain a licence (correct me please if I'm wrong). Should
we create a /LICENCE file or provide it as licence(7) to fix this?
