ghostscript with setpdfwrite setdistillerparams: Error: /undefined in .setpdfwrite

[milahu]

im trying to use ghostscript to compress a PDF file but when i add the option -c ".setpdfwrite <</AlwaysEmbed [ ]>> setdistillerparams" then ghostscript throws Error: /undefined in .setpdfwrite

so either a compile-time feature of ghostscript is missing or a runtime dependency is missing

based on https://stackoverflow.com/questions/10450120/optimize-pdf-files

$ gs -sDEVICE=pdfwrite -o output.pdf -c ".setpdfwrite <</AlwaysEmbed [ ]>> setdistillerparams" -f input.pdf

what causes the No such file or directory error?

strace

strace -f gs -sDEVICE=pdfwrite -o output.pdf -c ".setpdfwrite <</AlwaysEmbed [ ]>> setdistillerparams" -f input.pdf 2>&1 | less -S 

many "no such file" errors for the file Decoding/Unicode, which is provided by ghostscriptX in nixpkgs

$ nix-locate Decoding/Unicode
ghostscriptX.out                                137,541 r /nix/store/gczfw2iqzp95b4dlggvj87d03mciia0z-ghostscript-9.53.3/share/ghostscript/9.53.3/Resource/Decoding/Unicode

but ghostscriptX fails too
