I cloned guix git repository and tried make installation image, but get errors.

$ cd guix

$ guix system disk-image --image-size=1G gnu/system/install.scm

guix system: error: failed to load 'gnu/system/install.scm':

ice-9/boot-9.scm:2870:6: In procedure resolve-interface:

ice-9/boot-9.scm:2870:6: no code for module (gnu packages bootloaders)

Why? I did everything like the Manual says.
