OK, now I understand why what I tried didn't work and why you need the little 
"touch" trick.

Thanks.

No worries, it's not all straightforward so you're right to ask here.

It's especially non-straightforward when Apple breaks things, like removing the 
receipt of the command line tools periodically, which is what that problem 
hotlist entry is about.

Maybe your command line tools were incomplete for some reason, or were too old 
or too new, and reinstalling them has gotten you the right version.

I haven't updated the graphviz ports substantially in about 3 years so it's 
possible they're no longer compatible with some more recent Xcodes or command 
line tools. I clearly need to update them but with 3 years of changes built up 
it'll take a bit to see what all I need to do.

Thank you. Graphviz built after updating the command line tools.

I'm still not sure why this didn't work:

MrMuscle:~ mnewman$ xcode-select --install
xcode-select: error: command line tools are already installed, use "Software 
Update" to install updates

But, after doing that, Software Update didn't find any updates available. 

My browser history shows that after graphviz failed to build I visited:

Thanks again for your help. As you may have discovered, I need primary school 
level instructions.

Follow the instructions at that URL.

Show me the log. File a ticket at https://trac.macports.org/newticket and 
upload the compressed log there. If it's the same problem as in another ticket, 
I'll mark it as a duplicate and you can see what to do in that ticket.

I spent some time searching around, but all I found were other instance of 
graphviz related tickets, the details of which are beyond my ability to 
comprehend.

When graphviz builds, I get this warning:

Warning: cltversion: The Command Line Tools are installed, but MacPorts cannot 
determine the version.
Warning: cltversion: For a possible fix, please see: 
https://trac.macports.org/wiki/ProblemHotlist#reinstall-clt

So, I run this:

MrMuscle:~ mnewman$ xcode-select --install
xcode-select: error: command line tools are already installed, use "Software 
Update" to install updates

But, that doesn't fix the "MacPorts cannot determine the version" warning. 

Xcode is at Version 11.7 (11E801a)

The details:

The log file referred to is rather large (almost 1MB) and incomprehensible to 
me.

I don't know how to proceed from here.

Ticket 57137 is about the need for us to modify the xcode portgroup to set 
-derivedDataPath when using recent versions of Xcode. This is needed to prevent 
build failures of ports that build using xcodebuild. I do intent to look into 
that as I update graphviz to a more recent version.

graphviz-gui builds using xcodebuild, but graphviz does not. So that problem 
will not prevent graphviz from building.

There have been a few other reports lately of graphviz build failures for other 
reasons; if you're experiencing a graphviz build failure, see if one of them 
applies.
