Jeff,

No, you should not need to use an external libtiff.  The internal version
should be sufficient.  You might want to try duplicating the issue with
the "official" GDAL Win32 builds at:

   http://download.osgeo.org/gdal/win32/1.5/

If the problem occurs with that, you can file a detailed bug report,
including a tiffinfo and gdalinfo report on the source file.  If the
problem doesn't happen with the official build, then I suspect some details
of your build process are impacting things.

Best regards,
