[Gdal-dev] gdaladdo errors on Linux

[William Kyngesburye]

I've had similar problems before and it's a problem with the libtiff  
version.  Fixes for part of the problem are in libtiff CVS (and are  
included in my OSX frameworks).  It also was less of a problem in  
earlier libtiff versions (3.6, 3.7), but there may still be issues.

This looks slightly different than what I've seen before so it might  
not help, but it's worth a try.
