[gdal-dev] gdal and python problems

[Andreas Neumann]

Thank you very much - problem solved. There was an indeed an old version
of libgdal around (gdal1.5.2 - also self-compiled under /usr/local/lib)

The strange thing is that the svn trunk version reports as older
(libgdal.so.1.12.0) even if it is newer than gdal1.5.2, which reports as
libgdal.so.1.12.2

Thanks again for the hint,
Andreas
