Ok, I'm certified stupid and I'm sorry to have bothered people with better things to do. It turns out, using lddtree, that what actually depended on libicu version 63 was my personal copy of libboost-locale that I keep, together with other boost library, in /usr/local for development purposes. What I did was forgetting to re-compile the libraries after update.
