Hi,
graphics/pdf2djvu uses both print/poppler and graphics/exiv2, which
is a problem because newer poppler uses unique_ptr while exiv2 still
uses auto_ptr. There's a tweak in exiv2 to also use unique_ptr when
compiled with C++-11 or newer (include/exiv2/config.h), but to be
honest, I don't have the energy to try this and watch 20+ of other
ports to break on it.
So I'd really like to mark graphics/pdf2djvu as broken, maybe only
temporarily, to update print/poppler (to 23.05.0 for now).
Switching graphics/exiv2 to C++-11 and testing everything depending
on it can be done later, but I'm absolutely not sure wether this
can be done before the next release.
Ciao,
Kili
