this is the case. I intend to build the software without needing root 
rights. Any ideas on how to force the usage of the right gdal libraries?

Also Even Rouault seems to think that different versions are causing 
problems:

It could mean that you are compiling against GDAL 2.0 headers, but the linking
is done against GDAL 1.X instead.

I guess the OGR_GT_Flatten dependency must comes from the resolution of GDAL
2.0 "#define wkbFlatten(x)  OGR_GT_Flatten((OGRwkbGeometryType)(x))" from
ogr_core.h.

What can I do apart from?

--with-gdal=$prefix_opt/bin/gdal-config

Best, André
