Accessing a MacPorts tree from another [local] system

[Gregorio Litenstein]

Maybe you could try using a manual entry in fstab? Not the exact situation, but I've been running macports from a portable SSD for years, without issue.

The SSD has the macports installation under 'local' and I've added an entry in /etc/fstab so the drive is always mounted in /opt
