I have an old PC with FreeBSD 8.4 on it. I would like to install software from the ports collection but the computer doesn’t have the hardware necessary to access the internet. Is there a way to download a single port (or even the whole ports collection) on on another device that is running macOS or Linux, and then install it on the old computer via a USB drive?
[edit in response to Jim L.] At the moment, I’d like to install xorg, a window manager (probably Blackbox), emacs, and bash. My hard disk size is 8GB, and I don’t think that I’ll ever install more than 50MB of new software.
