<para>First you need a working PostGIS 1.3.5 or above database. Then you need to compile GDAL. Then you need to compile WKT Raster if there are no binaries available for your platform.
<para>The easiest is to download binaries for PostGIS and WKT Raster which are currently available for windows and latest versions of Mac OSX.
