I tend to agree with Alan. revdep-rebuild should help.
Additionally, if I were really intent on downgrading gcc, then I would
probably remove EVERY application unneeded to keep the machine running
down to and including X11, do the downgrade, rebuild the kernel and
reboot, do an emerge -e @world, make sure all that is working, and
only then start building apps. But that's just me...
Not exactly related, but I'm personally wondering what's driving the
need to downgrade. For kicks yesterday I rebuilt my laptop which
currently has audio apps as well as Blender on it with the latest
stable gcc. Everything rebuilt fine and everything I've tried seems to
run.
Good luck,
Mark
