 - Run:

   ...from the command line. This will do the build.
 
   The make system is fully parallelisable. If you have a multicore system,
   you probably want to do:
 
-    make -j8
+    make -j8        # or gmake -j8
 
   ...instead (substituting the right number of cores, of course). You can
   also shave a few seconds of the build time by using the -r flag.
