Technically you don't *need* to install MacPorts if all you want is Cairo. You could build it and it's dependencies from source.

</blockquote><br><div>You are correct; there is no GUI app called MacPorts. MacPorts is the command line program /opt/local/bin/port. </div><div><br></div><div>The installer should have set up your PATH so that you can run it by just typing "port" instead of that full path. </div><div><br></div><div>From your output above, I see you inadvertently entered MacPorts shell mode, indicated by the ">" prompt, by running "port" with no arguments. As it says, to exit that mode, type "quit" to get back to your normal shell's "$" prompt. At your normal shell "$" prompt, you can run "sudo port install cairo". </div></body></html>
