[gdal-dev] mod_python issue with libtiff

[Even Rouault]

Andreas,

I'm somehow happy to see that you've hit the warning. It means that it was 
usefull to add it and probably saved you headaches when things would have 
started to crash awfully...

Now, I'm afraid I cannot really help you more. There's something in your 
Apache that loads a libtiff 3.X... Don't you load other modules that could load 
libtiff indirectly ? A "ld foo.so | grep libtiff" on the potential .so python 
modules might help find the culprit.

Or perhaps if you move/rename /usr/lib/libtiff.so* to something else, the 
culprit will complain and you'll be able to identify it.
