Or, without a loop (easier to read and type, IMHO):

qfile -Cvq /usr/lib/udev | awk '{print "="$1}' | xargs emerge -pv

or, using gentoolkit instead of portage-utils (slower, but will not fail 
if the installed version of a package no longer exists):

equery belongs -n /usr/lib/udev | xargs emerge -pv
