Rudi,

For what it's worth the problem seems to be that while your libgdal.so was
upgraded, the Python bindings were not.  So the _gdal.so from the python
bindings is still looking for 1.8.

I'm not sure how you upgraded GDAL, but if you built it yourself just make
sure you also are building and installing the python bindings.  You might want
to get rid of the old ones (/usr/lib/python2.7/dist-packages/osgeo) first.

Best regards,
