I'm not sure what I think about this being contrary to the NetBSD goals
and the BSD-spirit license, so I'll only answer about why I've gathered
that folks don't like the GPL. It's because the GPL puts restrictions on
the source code for everything with which it's linked at build time (rules
different for libraries, and dynamically linked things aren't covered).
EVERYTHING has to be GPL'd, or you can't use GPL'd source.
AFAI can tell, the snipped copyright says NOTHING about the other source
with which you might compile that source.

That would get a bit silly... :-)

I'm not sure.
