You could either rerun ./configure on the machine, so that it
substitutes the shebang with the right file name for =E2=80=98guile=E2=80=
=99.

Alternately, you could copy the profile from the first machine to the
second one, along the lines of the example at:

  https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-archive.=
html

In addition, you would need to make
/var/guix/profiles/per-user/$USER/guix-profile-XXX-link point to the
imported profile (currently this has to be done manually.)

HTH!
