If you want to compile OPAL/JAVA yourself, this requires that JAVACC is found in your path, and that PIZZA is available. JAVACC can be found at http://www.metamata.com/JavaCC/. PIZZA can be obtained at http://www.cis.unisa.edu.au/~pizza/. Note that these tools are not required for proper installation, they are needed only for developers of OPAL/JAVA.
