For everything that is NOT in /usr/local you can use this little script
to find out what old cruft you have in your tree.

It finds all of your directories/files (less those it's told to skip) and
then diffs it against the current distribution sets.   The output, in unidiff
format, lists with a + those things you have extra and a - those things you
don't have or told the find to skip.   It requires the source -- at least
/usr/src/distrib/sets -- to work.   Modify the list of dirs to exclude for
your system.

Note: the distribution sets often lag recent changes by a day or
three, so don't be in too much of a hurry to delete something unless
you are sure that it is old cruft that is no longer needed.

Enjoy,
