Ah, yes the /lib/lib32/lib64 fs consolidation/migration. This needs to be managed too. In this occasion a fresh install would be the easiest approach, inc. moving portage to /var, all of which will arrive with a new Stage 3. The last time I upgraded an old unmaintained Gentoo installation was years ago. The underlying architecture had not changed much then, but it still took me a week or so firefighting with gcc and what not.
