Problem is possibly linked with icu.
Try re-building dev-libs/re2.
That did the trick... This is SOLVED for me, but it should be probably more "automatic" in portage (if it is possible, please enlighten me in this topic if not...) Thank you S
dev-libs/re2 has a slot-operator dependency on dev-libs/icu, so the rebuild should have been automatic. It is hard to say why this failed for you.
