Hello,

some more info since I still do not understand where *.gz files are
coming from

If I build the package with "--keep-failed" I can inspect the kept
building dir /home/guix-builder/guix-build-ruby-taskjuggler-3.7.1.drv-4,
and there are no *.gz files

I've found and tried this:

--8<---------------cut here---------------start------------->8---

                  (add-after 'unpack 'unpack-bundled-sources
                    (lambda _
                      (with-directory-excursion "."
                        (invoke "tar" "xf" "checksums.yaml.gz"))))

--8<---------------cut here---------------end--------------->8---

but it fails:

--8<---------------cut here---------------start------------->8---

starting phase `unpack-bundled-sources'
tar: checksums.yaml.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
command "tar" "xf" "checksums.yaml.gz" failed with status 2

--8<---------------cut here---------------end--------------->8---

I still don't understand why appying a patch (with "(patches
(search-patches....))" in (source (origin...)) is failing.

Thanks! Giovanni
