I'm not sure why you would want to do this, but

sort /var/db/portsnap/INDEX |
	comm -3 - /usr/ports/.portsnap.INDEX |
	cut -f 1 -d '|'

should output the files/directories being added and removed in the
1st and 2nd columns respectively.  (Something which is modified
will appear in both columns, of course.)
