Near the bottom of http://cr.yp.to/softwarelaw.html Dr. Bernstein
explains as follows:

He provides the source code for free download and appears proud of
the almost two million send level domains serving their records with
tinydns ( http://cr.yp.to/surveys/dns1.html ). According to his
published statements he interprets the relevant United States federal
law to mean that you do not need a license to compile and run source
code that you have legally acquired.  DJB apparently believes that
the whole paradigm of needing a license before you can run a program
is in error and he does not appear to be about to encourage this
common mistake by declaring some kind of license terms.

Freshmeat rightly lists the license for DJBDNS as "freeware"

with a link to a page defining the term.
