Note that the test that disabled the GTiff driver when both internal and external libtiff are detected has been relaxed in GDAL 1.8.1 by commit http://trac.osgeo.org/gdal/changeset/22461/branches/1.8/gdal/frmts/gtiff since it seemed to be an annoyance for quite a number of people where the mix of libtiff versions happened to work before. So the driver is no longer disabled, but a warning is still emitted since depending on the linking order between GDAL and external libtiff, you could observe crashes. A better solution has been found and will be available in GDAL 1.9.0.
