* Platform
Fedora 26 x86_64

* Version
guix (GNU Guix) bad12e839c2f7823c45aa0121f7d5c9bb70905b7


I have the script running on Fedora with dependencies built by dnf, but not guix.
I searched around, tried to find out what is missing.
But it doesn't seem to be a problem caused by missing packages.

Using Guix 3694c0d, it seems to work.
