You need to build MacPorts from source so it knows to live in a different prefix [1]. Then, add the prefix to your PATH and whenever you want to use MacPorts simply specify the full path to the one you want:
/opt/local/bin/port
/opt/other-local/bin/port

Btw, is highly recommended to NOT use /usr/local because several programs are hardcoded to use what is found in that path; by placing stuff there you will effectively be cross-contaminating various packages you install.

Keep in mind, a non-standard prefix is prevented from using pre-built archives from packages.macports.org.
