Usually when a Debian package works while the Guix package fails, I
examine the Debian packaging, especially the file at 'debian/rules'.

You can find those on the package web page [0] as the [...]debian.tar.xz
file and surely through some command-line tool.

[0] Make sure to select your Debian release (Jessie, Stretch, etc):
https://packages.debian.org/stretch/guile-2.0
