Our pdfposter port is outdated, however updating to the latest version 0.8.1 doesn't fix it. Here is the upstream bug report: ​https://gitlab.com/pdftools/pdfposter/-/issues/23

In 611e3329f010f363d2fd6f4187b57c5143ce94e5/macports-ports (master):

pdfposter: Update to 0.8.1; use python312; port to pypdf

Closes: #69497

Inspired by ​https://gitlab.com/pdftools/pdfposter/-/merge_requests/7 I have tried to update the port to 0.8.1 and include a patch to make it work with pypdf instead of PyPDF2. Does it work for you? When I tried it, I got PDFs that only contained blank pages. I don't know if that's because I don't know how to use pdfposter or it's broken or these changes are insufficient.

i tested 0.8.1 on several pdfs and the result is always: right number of empty white pages.
