This bug is for myself as a reference and to close it once we have fixed the comment in the graphviz package. If you read https://github.com/ellson/graphviz/issues/1267 you'll find out that ksh-93, which we don't have (yet) is the shell which should be able to run the test suite of graphviz. I'm currently debugging the build of ksh-93 and I also need to read every header of it to check if we have one bit of AT&T proprietary copyright in there. As fedora packages it, the chances are high that it can just be used as-is, but we should check it nevertheless. -- ng0 GnuPG: A88C8ADD129828D7EAC02E52E22F9BBFEE348588 GnuPG: https://n0is.noblogs.org/my-keys https://www.infotropique.org https://krosos.org
