Please run 'guix style' on this.  Also, at run time,  I get:

--8<---------------cut here---------------start------------->8---
$ /gnu/store/j2gp8aqd9xiwpwybwf5zj1zrc92mf8y1-kompare-22.08.1/bin/kompare

and cannot use it.  Is it expected to only work inside a KDE
environment?

This one appears to run fine on my side.

Could you address the issues here (at least the typos and guix style),
but hopefully add a comment explaining the environment requirements for
kcompare to run and send a v2, or even a fix! :-)
