Reinstalling ports meant building them, and this was going fine for many of them. In the process of installing pinentry-mac this error popped up:

I've tried to reinstall the command line tools both via that dialog box (which claims to have reinstalled them) and via xcode-select --install (which tells me they are already installed). Software update says everything is up to date. However, when I enter 'make' at the command line I get the same error:

Make sure you've installed a Tahoe-compatible version of Xcode and have opened it and performed the first-run installation and agreed to the license, if necessary.

And make sure you have a compatible version of the command line tools. If you're upgrading from an older OS, and a correspondingly older command line tools, it's possible you still have that older CLT and the OS has not prompted you to upgrade them due to the bug described here:
