Graphviz build fails

[David Nicholls]

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latest Sonoma 14.7.1 on an Intel Mac, the most recent Xcode tools and Macports 2.10.4 self updated, I ran port upgrade outdated, and after a few port upgrades, I got this message: 

sudo port upgrade outdated

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.
