Prefix those commands with "sudo" for normal root MacPorts installations. 

I believe I read somewhere that the python community recommends that "python" always be python 2.x, never python 3.x. Programs that want to use python 3.x should use the program name "python3". If "port select python" currently allows versions of python 3.x to be selected, we may want to change that.
