Well, I guess it comes from ’unpack’; which reads:

--8<---------------cut here---------------start------------->8---
(define* (unpack #:key source #:allow-other-keys)
  "Unpack SOURCE into the build directory.  SOURCE may be a compressed
archive, a directory, or an Emacs Lisp file."
  (if (string-suffix? ".el" source)
      (begin
        (mkdir "source")
        (chdir "source")
        (copy-file source (store-file->elisp-source-file source))
        #t)
      (gnu:unpack #:source source)))
--8<---------------cut here---------------end--------------->8---

Well, I guess again that the ’source’ should contain something like,

    (file-name (git-file-name name version)

to avoid the issue.  But the naive approach does not work with
’local-file’.


Cheers,
simon
