Once things are built by the macports user, MacPorts trusts itself to
install them: this is why they're owned by root when you run MacPorts with
sudo. It is only during the specific phases of the whole process that
MacPorts will drop its privileges to the macports users, and afterwards
pick them back up.

One can also build ports without sudo, and they'll be built and installed
in your $HOME; one can compile MacPorts itself to live entirely in your

I'd assume "can be". You can change this user by compiling MacPorts
itself: check out MacPort's own ./configure options. There might be a
macports.conf setting for this, but I cannot authoritatively answer that
one :-) Ryan knows perhaps?

I will again assume here: no. I think it will simply test that it has
permission to do what it is trying to do, and give you an error if it
cannot complete it. Ryan, do you know better? :-)
