You don't actually need to rebuild all you ports right away, but you do need to do so eventually (i.e., before you start building more pots). Your old ports are linked against the old libraries, and if you get something linked against a mix of old (e.g., 7.x) and new (e.g., 8.x) libraries, it won't work. But then, that's covered in the upgrade instructions also... -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/
