With the latest Sonoma 14.7.1 on an Intel Mac, the most recent Xcode tools and Macports 2.10.4 self updated, I ran port upgrade outdated, and after a few port upgrades, I got this message:
sudo port upgrade outdated ---> Computing dependencies for graphviz ---> Fetching archive for graphviz ---> Attempting to fetch graphviz-9.0.0_1+pangocairo+x11.darwin_23.x86_64.tbz2 from https://packages.macports.org/graphviz ---> Attempting to fetch graphviz-9.0.0_1+pangocairo+x11.darwin_23.x86_64.tbz2 from http://mirror.fcix.net/macports/packages/graphviz ---> Attempting to fetch graphviz-9.0.0_1+pangocairo+x11.darwin_23.x86_64.tbz2 from https://kmq.jp.packages.macports.org/graphviz ---> Building graphviz Error: Failed to build graphviz: command execution failed Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_graphics_graphviz/graphviz/main.log for details. Any suggestions? Also, I've forgotten how to proceed with the update and bypass the problem install, as it's been a long time since this problem last occurred. Advice appreciated.
