Tangentially, I had to upgrade cups-filters due to an incompatibility
with the new version of Poppler.  I had a brief look at these changes
and they still seemed to be in effect, but please verify that it works!

I started a new evaluation about an hour ago, I think it can be merged
if everything builds this time.  Readers are encouraged to test it on
their systems once substitutes are available and report any problems :)
