Failing to build my package definition of emacs-greader-mode.

[Yuval Langer]

I am trying to upgrade my package definition for the greader [1] [2]
text-to-speech mode.

My package definition is in:

https://codeberg.org/kakafarm/guix-kakafarm-channel/src/branch/upgrade-greader-to-0-11-18/kakafarm/packages/emacs-xyz.scm#L83

I get an error in the build phase saying that the function
greader-get-language cannot be found.

The function is defined in ./greader.el, and used in ./greader-dict.el.

I see that ./greader-dict.el has a (require 'greader), so I would have
imaged that the functions defined in ./greader.el would be available
in ./greader-dict.el.

Does anyone know how to fix this?
