PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS). To disable raster support and eliminate the gdal dependency, set RASTER=no. If you choose this path, be aware that postgis will still need the two dependencies that gdal relies on, proj and geos. To disable the GTK-based graphical interface for shp2pgsql, set GUI=no. This SlackBuild does not build the PostGIS JDBC driver since the build requires Apache Maven to download dependencies at build time. The optional dependencies needed to build the driver are: apache-ant, apache-maven, and postgres-jdbc.
