Several gnome ports seem to be failing to update with a similar error all of a sudden:
config.status: error: Something went wrong bootstrapping makefile fragments for automatic dependency tracking. Try re-running configure with the '--disable-dependency-tracking' option to at least be able to build the package (albeit without support for automatic dependency tracking). e.g. https://lists.macports.org/pipermail/macports-tickets/2018-April/242217.html and several other ports on my machine at home. At this moment, I'm updating some PPC machines, if that is relevant to this error. Adding the suggested configure flag "--disable-dependency-tracking" to each Portfile seems to fix them. Did something change recently? Ken
