# However, /usr/lib/X11 is symlinked to /usr/X11R6/lib/X11, which
# also happens to be the "correct" path for installing files, while
# /usr/lib/X11 is not.
# There is a problem with dpkg in upgrading packages in that it fails
# to recognize when /usr/lib/X11 and /usr/X11R6/lib/X11 are the same.
# It therefore unpacks this package and immediately removes all its
# files as a side-effect of removing files from the old package.
# Until (or unless) this is fixed, we must make an explicit distinction
# for dpkg between the two directories, and later remove it.
# This is horrible, horrible, horrible, sigh.
