   2. Check the sanity of doing a build with your current system:
-       gnumake sanity
+       make sanity
      See README-builds.html if you run into problems.
   
   3. Do a complete build of the OpenJDK:
-       gnumake all
+       make all
      The resulting JDK image should be found in build/*/j2sdk-image
