I think that if sub latestbuilds simply accepts a nixname we are set! 

Add the Perl lines 

   my $nixname = $c->request->params->{nixname};
   $filter->{nixname} = $nixname if ! $nixname eq "";

So we can do
"http://hydra.gnu.org/api/buildToHash?nixname=ruby-2.2.3";, assuming
the DB rec has a field named nixname - which I think it has, because
the result already has the column.
