Adding guile-fibers to the list of packages for guix shell is enough to
get rid of the error, so I assume dependencies are not configured
correctly for the shepherd package.

Interesting is however that the dependency is listed in guix search:

--8<---------------cut here---------------start------------->8---
$ guix search shepherd | head -n 20 | grep dependencies
dependencies: guile-fibers <at> 1.3.1 guile <at> 3.0.9 gzip <at> 1.13 pkg-config <at> 0.29.2
--8<---------------cut here---------------end--------------->8---

So, something is wrong, but not fully sure what.

Tomas
