Since Texinfo 7.0 (available in unstable) it’s now possible to produce epub files from texinfo. I’m trying to produce an epub file for the Emacs lisp intro book, but when I try to generate it I get an error
$ TEXINPUTS=".:.:" MAKEINFO="makeinfo --force --enable-encoding -I ." texi2any --epub3 emacs-lisp-intro.texi
texi2any: Archive::Zip is required for EPUB file output
but zip is installed on my system
$ zip --version

When I asked in #emacs@libera.chat someone suggested that it’s probably a Perl library that’s missing.
I looked at texinfo in the nixpkgs tree and I saw that texinfo is a dependency for gcc. The function doesn’t follow the usual pattern for applications, and I don’t want to muck around with low level dependencies. What should we do?
