Hello Dave,

         You were right!! I have re-compile my gdal library using the
external libtiff and it runs correctly.


         However, I had some problems trying to compile gdal-1.8.1 against
an external libtiff and libgeotiff. There is a problem with libtool when
gdal is generating libgdal.lai because gdal set a wrong path to the
external libtiff. To avoid the problem, it is necessary to use system
libtool.

         Thank you very much!!!

Best Regards,

Jorge
