fetching binaries without installing

["Justin C. Sherrill" <justin%shiningsilence.com@localhost>]

I'm working on building a DragonFly CD, and I want to include X and some
other programs on it.  To do that, I need to have the pkgsrc packages
included on the CD.

I can install from binaries, and I can 'make fetch', but neither of those
do what I want: fetch a pkgsrc binary package (in this case, from Joerg's
binary site) and all its dependencies, without installing it.  Is there a
simple way to do this without either building everything first or having
to fetch each individual dependency?
