          (add-after 'unpack 'fix-failing-tests
            (lambda _
              (substitute* "tests/test_core.py"
                (("(core\\.load_lib)\\((\\[gllib\\], \\[\\])\\)"
                  all fun args)
                 (string-append "raises(ValueError, " fun ", " args ")")))
              (delete-file "tests/test_freeimage.py"))))))

It looks the whole [arguments] block may be removed and skip test
logic applied in #:test-flags as the package uses python-pytest e.g.
"--ignore=tests/test_freeimage.py" or "-k not <test-name>".

+      #:tests? #f ; tests need internet and are not distributed in PyPI

Maybe install from Git?
<https://github.com/imageio/imageio-freeimage/blob/master/tests/test_freeimage.py>
the only one tests file which does not require urllib or requrests.

 (symlink (search-input-file inputs "lib/libfreeimage.so")
--8<---------------cut here---------------end--------------->8---
Maybe swap to #$(this-package-input "<package>") instead?
