Thanks. So...

punkish at lucknow ~$port installed gdal
The following ports are currently installed:
  gdal @1.8.0_0+expat
  gdal @1.8.0_1+curl+expat+geos+netcdf+postgresql90+python27+spatialite+sqlite3 (active)
  gdal @1.8.0_1+expat


So, it seems I have multiple versions of gdal installed, and the PostGIS configure script is probably picking up the wrong version. Looking above, how do I uninstall `gdal @1.8.0_0+expat`. And, what is the difference between the next two?
