https://trac.macports.org/wiki/howto/ShareArchives2 might help (you'll copy files over but won't have to build from scratch. > Any alternatives which will actually work as intended? I.e.

Yon can build base from source and point macports point to a different directory. I had a version of MacPorts working where /opt/local was a symlink some time ago (I had a local patch to fixup some of the problems, but I can't find it now). IIRC setting prefix in macports.conf made things mostly work. -- Daniel J. Luke
