I'm assuming "Xbox" was due to auto-correct :-)

port is informing you that the build tools aren't installed correctly
and then giving you the instructions for installing those tools.

In this case, everything you installed was available as a pre-compiled
binary so you didn't need to compile anything yourself and didn't need
to use those tools. If you install other ports in the future those
builds might fail if you don't install the command line tools or the
rest of Xcode.

If you only need cairo, you are indeed all set for now.
