Problem to install RPM's and/or run dot on Centos 6

Thanks. I filed an issue for the first problem: Problem to install RPM’s on Centos 6 (#1695) · Issues · graphviz / graphviz · GitLab

  1. Will you attempt a fix?
  2. Yes, there is clearly something fishy with the dependencies. I tried to install one package at the time, but it was impossible since there seems to be circular dependencies. I ended up installing them all in one go to avoid it.
