The gimp-print package is old, as upstream has renamed to gutenprint and
bumped to version 5.  The source looks organized in the same way,
so this shouldn't be hard.

I am inclined to adjust all of these to 5 and reimport as
gutenprint-foo.  Or should we keep the package as gimp-print?

This seems like a long overdue update.  Is there any reason it hasn't
happened, other than lack of time?  Does anyone feel responsible
(MAINTAINER is pkgsrc-users@) -- should I just go ahead when I find
spare time?
