  * *PostgreSQL and PostGIS* binaries - use [kyngchaos.com](http://www.kyngchaos.com/wiki/software:postgres) or from source:
   * You can build PostgreSQL from source just like any other linux/unix system - [Postgres Docs](http://www.postgresql.org/docs/8.3/interactive/install-procedure.html)
   * Next build PostGIS source (Install GEOS first if you wish to use Spatial Operations in Postgis separately - [http://code.djangoproject.com/wiki/GeoDjangoInstall#GEOS])
 
+```sh
     $ wget http://postgis.refractions.net/download/postgis-1.3.4.tar.gz
     $ tar xzf postgis-1.3.4.tar.gz
     $ cd postgis-1.3.4
     $ ./configure --with-geos --with-proj # these flags are recommend but not needed for Mapnik
     $ make
     # make install
+```
 
   * Alternatively, you may install PostgreSQL and PostGIS using MacPorts. First, run
 
+```sh
     $ sudo port install postgresql83
     $ sudo port install postgis
+```
+
   * Next, modify the SConstruct file to point to the libraries and header files installed by port. Change the lines that list PGSQL to:
 
+```
     opts.Add(PathOption('PGSQL_INCLUDES', 'Search path for PostgreSQL include files', '/opt/local/include/postgresql83'))
     opts.Add(PathOption('PGSQL_LIBS', 'Search path for PostgreSQL library files', '/opt/local/lib/postgresql83'))
+```
+
   * See [[MacPostGIS_Setup]] for setup instructions.
  * *GDAL* binary frameworks - use [kyngchaos.com](http://www.kyngchaos.com/wiki/software:frameworks) or build from source:
 
+```sh
     $ wget http://download.osgeo.org/gdal/gdal-1.5.0.tar.gz
     $ tar xzf gdal-1.5.0.tar.gz
