My standard answer (and huge time-saver) is to install
sysutils/bsdasminscripts and do the following. This example is for
pcre and icu

% pkg_libchk -o | grep -E "libpcre|libicu" | cut -d: -f1 | sort | uniq
> pcre-updates.txt
% portmaster `cat pcre-updates.txt`

This will only update any port once and will only update ports that
really need it.
