@pkgdir and share/emacs/emacs21.4/leim

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

After a binary install of emacs(21)-nox11 on a 4.0.1 machine, emacs complains 
Warning: Lisp directory `/usr/pkg/share/emacs/21.4/leim' does not exist.
The relevant PLIST contains @pkgdir share/emacs/${EMACSVERSION}/leim, but 
nothing else. The Guide says:

If a package needs an empty directory to work, create the directory during 
installation as usual, and also add an entry to the PLIST:

Does this mean that pkg_add should create the directory because of the @pkgdir 
command or does the PLIST need an additional entry?
