buildprep is optional.  We already agreed to make gnuplot optional in
buildprep.

Next?

It makes plot files and dumps statistics summaries.  The plots can then
be plotted elsewrhere.  I forsee a future option where it just outputs the
text summaries.  Just way down on my list.

Some will, some will not.  Some might use ssh to run a server copy of
gnuplot from the ntpd host.  Do with it as you wish.

The plot files are potentially a lot smaller.
