It works for me on a foreign distro.  This is what I see:

--8<---------------cut here---------------start------------->8---
address@hidden:~$ guix package --list-installed | grep guix
guix    0.12.0-6.73a4   out     
/gnu/store/3xwb1alcv5xd2zgcxp1d1bqqgv0afxj2-guix-0.12.0-6.73a4
address@hidden:~$ env | grep GUILE
GUILE_LOAD_PATH=/home/marusich/.guix-profile/share/guile/site/2.0
GUILE_LOAD_COMPILED_PATH=/home/marusich/.guix-profile/lib/guile/2.0/site-ccache:/home/marusich/.guix-profile/share/guile/site/2.0
address@hidden:~$ find -L $(env | grep GUILE | cut -d = -f 2 | tr : '\n' | sort 
| uniq) -name packages.scm
/home/marusich/.guix-profile/share/guile/site/2.0/guix/packages.scm

Can you share the output of similar commands on your system?

By the way, I see you're using Guile 2.2.  Does this same problem occur
when using Guile 2.0?  I think Guix is still compiled using Guile 2.0,
so I get warnings when trying to import (guix packages) using Guile 2.2.
