liftiff needs to be built with -headerpad_max_install_named. Seehttp://trac.macports.org/changeset/103701
where I fixed this in MacPorts. Since I didn't increase the revision, if
you were using MacPorts to install your copy of libtiff, you need to run
sudo port selfupdate
sudo port -s -n upgrade --force tiff
to get the change.
