This means that you need to make sure that the target machine has (guix)
in its load path.

The test is to run something like:

  $ ssh localhost env |grep GUILE_
  GUILE_LOAD_COMPILED_PATH=/home/ludo/.guix-profile/lib/guile/2.2/site-ccache:/home/ludo/.guix-profile/share/guile/site/2.2:/run/current-system/profile/lib/guile/2.2/site-ccache:/run/current-system/profile/share/guile/site/2.2
  GUILE_LOAD_PATH=/home/ludo/.guix-profile/share/guile/site/2.2:/run/current-system/profile/share/guile/site/2.2

and you should see /run/current-system/profile/share/guile/site/2.2.  If
not, you’ll have to add it somehow.

(It’s unfortunate that setting up offloading remains error-prone, but
that’s a different story!).

HTH,
Ludo’.
