ddjvu subsample output does not match expected input of djvumake
I had to try a lot of 'newer' Ghostscript-versions before I found the newest one that still compiles. The newest version Ghostscript 9.54 from 9.53.0 and up has a dcontrib.mak instead of a contrib.mak in /devices, so again the script fails. There is another compilation error from 9.27 and up. GS 9.26 PDL compiles and links fine on Linux (Ubuntu) Mint 20.4 as does the original GS 9.22.
