Hi, I might be wrong, but I do not believe it is possible to temporarily change the install prefix, for a single port.
Most probably you will need to start a new installation, using a custom installation prefix, from scratch. see https://www.macports.org/install.php#source <https://www.macports.org/install.php#source> on installing from source, which you will need to do to change the installation prefix, as its a configure time option.
