Oh - duh.

Would it be enough to do a regular pkg build of the new compiler, then
check the .so version of libstdc++ used by that compiler, run a script
to find all uses of older libstdc++ in PREFIX and show a pkg_delete -r
invocation that would kill all those pkgs? (And left as an exercise: use
the users prefered update method to get new versions of the updated pkgs
back, if needed).

Or do we end up with mixed libstdc++ in the new gcc pkg already?
