Add X11BASE/lib/mozilla into LD_LIBRARY_PATH along with
X11BASE/lib/mozilla-embed, so that Nautilus compiled with WITH_FULL_MOZILLA
works as well. Don't bump PORTREVISION, because WITH_FULL_MOZILLA isn't on by
default.
Tech gnome-session how to set-up a LD_LIBRARY_PATH, so that mozilla component
of nautilus Just Works[tm], without the need to customize environment. Remove
appropriate comment from post-install section of nautilus' Makefile.
