So they changed the program, and we should follow, although I am not that happy about it - for a "more standard" pdf reader, I might as well switch to evince or okular. So I would like to ask a help-guix type question (but keep it here since the context is already set up): How can I personally keep the old variant? Should I create a custom channel with xpdf@4.02? Or even xpdf@5 to have a higher version number, but with the old 4.02 package code and source? Or a manifest including some time-machine thing, or a personal package transformation that compiles xpdf --with-source=...? Andreas
