 MacPorts must be [https://www.macports.org/install.php installed] in a version configured for macOS 15 Sequoia. If you update from an older OS version, you need to run `port migrate` to reinstall MacPorts base and installed ports that are not OS-independent (see link above).
 
-Ensure you have Xcode 16.0 or greater installed and selected (e.g. `sudo xcode-select -s /Applications/Xcode.app/Contents/Developer`), and that you have the command line tools installed (`xcode-select --install`). You also have to agree to the license by running `sudo xcodebuild -license`.

(CLTs should probably be avoided for now, see below.) You also have to agree to the license by running `sudo xcodebuild -license`. 
 
 There have been reports that the `-license` option might not be sufficient alone, and following command might be required to agree to the license: `sudo xcodebuild -runFirstLaunch`

+== Compiling C++ fails ==
+
+The C++ compiler in the Command Line Tools for Xcode 16 appears to be broken on Sequoia; it does not look in the correct place for C++ headers. The majority of ports that contain C++ code will likely fail to build as a result.
+
+The workaround is to use the compiler in the Xcode app. Either not installing the CLTs in the first place, or deleting `/Library/Developer/CommandLineTools` if they are already installed, will force MacPorts to use Xcode instead.
