[HEADS UP] pkg_radd on 2.3 and older systems

[Justin C. Sherrill]

If you have a system older than 2.4, pkg_radd uses an old path to find
files.  Applying the changes here:

http://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/3d62c9e33361b5901e858332066162cc93afc27b

will make it work with the current layout, and it means I can get rid of
the old top level links, which I'll do momentarily.

(I figure this only affects a few people running older systems, who may
have changed the path already anyway...)
