I installed zathura and zathura-pdf-mupdf — is zathura supposed to be
modular? In any case, I got the same errors.

But, when I replaced zathura-pdf-mupdf with zathura-pdf-poppler and made
sure the requisite environment variables were set (`guix package
--search-paths`), PDF reading worked for me.

I didn't test reading EPUB files. Is zathura supposed to read EPUBs?

I was able to reproduce this as well.

It looks like zathura-pdf-mupdf needs to be built with
-Dlink_external=true.  I got this to work, but got stuck with a problem
in libmupdf.so, which seems to have symbols that are provided by
libmupdfthird.so.

It seems as if something’s not right with how these libraries are
linked.
