In a fresh 12.0 VM + pkg install pdfsandwich
Running pdfsandwich fails on not finding the pdfunite program.
Installing poppler-utils is a fix or workaround
(In reply to Poul-Henning Kamp from comment #0)
textproc/pdfsandwich already has pdfunite:graphics/poppler-utils in RUN_DEPENDS.
This has never been MFQed. I've sent the MFQ request.
The fix is in the ports tree.
I've never received the MFQ approval.
