MarsSeed [1] filed a deletion request for pdfscissors [2]: This tool itself was last updated in 2011. Since that time, upstream URL is gone, source tarball got put behind loginwall and cannot be downloaded.
I would suggest to delete this if not salvageable. There are dozens of working of PDF editing/cutting/modifying tools available nowadays. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/pdfscissors/
