It's not listed at as being public domain at:

  http://cr.yp.to/distributors.html

...so I would presume it's the same situation as qmail/djbdns/etc
before they were released into the public domain, that is, license
free software.  You can download it, use it, distribute unmodified
versions, distribute patches, but no distributing modified versions
(though you can probably distribute an original tarball with a script
that applies patches) and no derivative works.

As to djb's intentions, I can only speculate.  Perhaps he hasn't
gotten around to putting into the public domain yet, maybe he will
someday.  Or maybe he prefers the current situation for some reason.
You could mail him and ask, but I wouldn't hold your breath waiting
for a reply.
