Yes, it seems that we are now using

  print -dpdf

to create the PDF files and the resulting output is not cropped
tightly around teh bounding box of the figure.

If that is what the -dpdf option is supposed to do, then I guess we
should probably just have the  Makefile produce .eps files and then
convert them to formats we need instead of using Octave's print
function to generate the various formats.
