Hi Guix, the tests for this package cannot easily be fixed by #:phases (modify-phases %standard-phases (add-after 'unpack 'fix-tests (lambda _ (substitute* "auparse/test/auparse_test.ref" (("\\(root\\)") "(unknown(0))")) #t))) because for *some* of them “(root)” is returned (while for *most* of them its “(unknown(0))”). Ideas on how to fix the tests are very welcome! ~~ Ricardo
