 I'm not really familiar with the state of JavaScript in Guix. However,
 Guix generally only includes packages built from source.

If I understand correctly, we already have a mathjax package built from
source. See js-mathjax.

Mathjax 3 is a complete rewrite of mathjax 2. I had thought js-mathjax was just the component files too and not truely built from source. Maybe I was wrong. Currently, building this from the true source requires a huge number of js packages and we haven't got a npm importer and full JavaScript bootstrap yet so I wasn't sure what to do. If you like we can ignore this and I can modify calibre to disable mathjax for now since I don't think it works with the old mathjax 2. I would like to work on getting more JavaScript in to guix properly
