The libgeotiff is fine, but unfortunately depends on proj.4 --- and the 
proj.4 installation for Ubuntu (and all Debian distros) is compiled 
incorrectly without NAD datum shift grids.  This can be a problem.

If you are using proj.4 for *anything* other than Xastir (which requires it
solely for libgeotiff, but doesn't use it for datum shifting), you need to
build proj.4 from sources and do so by unpacking the NAD datum shift grids
in the "nad" directory first.

Just a warning.  This doesn't impact Xastir directly, but does impact *anything*
else that uses proj.4 (QGIS, GRASS, or GDAL tools).  If you build proj.4 from
source, you also need to build libgeotiff from source -- otherwise the 
package management system will install the broken one anyway.
