[postgis-users] GDALFPolygonize undefined in rtpostgis-2.0

[Bborie Park]

Jack,

My guess is that there are more than one GDAL libraries on your system
and the GDAL library used for testing the presence of GDAFPolygonize is
different than the GDAL library attempting to be loaded.  Since you
built postgis from source, you should be able to check config.log and
inspect the lines regarding the GDALFPolygonize test.
