If you just have a one-off command you want to run in the secondary installation, you could call it by its full path, e.g. /somewhere/bin/port. If you're settling down for lots of work in the secondary installation, you could "export PATH=/somewhere/bin:$PATH" in your terminal, but when I do that, I get confused about which terminal window has what set. You could change that terminal window's color to remind you it's different.
