Hello! I wanted to install biber 2.10 but Guix has and never had a package for it (I think). So I think of rewriting the existing package.
I see no --with-version option for `guix build`. I tried guix environment --ad-hoc -e '(begin (use-modules (guix packages) (gnu packages tex)) (package (inherit biber) (version "2.10")))' but it still uses the source for the current biber 2.12 instead of biber 2.10. I suppose Guix’ record implementation is “hygienic” and never refers to a changed version. What to do? Regards, Florian
