Hello,

You should be able to use =E2=80=9Cguix build foo --with-source=3D./foo=E2=
=80=9D (note
that the directory name must match the package name).

  https://www.gnu.org/software/guix/manual/html_node/Package-Transformation=
-Options.html

It should work (you must import (guix gexp) to get =E2=80=98local-file=E2=
=80=99).

Can you share what errors you got?

HTH,
Ludo=E2=80=99.
