Comment:

 As per http://guide.macports.org/#using.port.install, you need to run port
 install commands with sudo. So, "sudo port install -v pgplot +darwin_i386
 +aqt +demos".

 Maybe this should be made clear in the error message when port install is
 invoked and runs into permissions errors like this?
