Also, version "0.1" seems to be incorrect here, since there aren't any releases at all. So I'd start at "0.0". I could be wrong, but I don't think that the auto-updater (guix refresh -u) understands let-bound versions (let-bound commits and revisions are ok though), and you're only using the 'version' variable in a single place, so I'd move it to the 'version' field of the package record. Greetings, Maxime.
