About rasterlang and GDAL

The rasterlang QGIS plugin refused to work, complaining about a self-compiled GDAL with almost everything enabled. Investigation showed that in addition to all GDAL dependencies, the NumPy package must also be installed. Otherwise you some things will not work.

NumPy is needed to build gdal_array: a small but essential module used to represent images as arrays and then do all sorts of naughty things with them.

After installing NumPy, rebuilding and updating the GDAL package, everything worked.
