Because of changes that Apple made starting with macOS Mojave, some work was put into \
MacPorts to make it work with only an Xcode installation, so that a command line \
tools installation was not also necessary. So having just Xcode should work in most \
cases.

However if you previously had both Xcode and the command line tools installed before \
upgrading macOS, then after upgrading macOS you should upgrade both Xcode and the \
command line tools. Upgrading only one or the other will leave you with a mismatch \
which could cause problems.

`xcode-select --install` presents you with a dialog box through which you can \
initiate either an installation of Xcode or an installation of the command line \
tools. If you want to do both, initiate `xcode-select --install` a second time after \
you've finished doing the first one.

If for some reason the download via `xcode-select` isn't working, you can download \
both from https://developer.apple.com/download/more/
