Ok, this is due to the fact that apr was compiled with db-4.0 and you are now probably using db-4.1. Try to rebuild apache2 and try again.
A rebuild fixed it... Sorry for not trying that before reporting.
No problem, this at least reminds us that someday portage should be able to figure the rebuild requirement out itself.
