cacao 0.97-4 (powerpc binary) in ubuntu gutsy

 CACAO is a free virtual machine for running Java programs
 It has a state-of-the-art optimizing JIT compiler, with
 performance competitive with that of the Sun HotSpot product JVM.
 .
 Note that CACAO is not officially certified as Java. (Nor is any
 other free virtual machine.) This is because some aspects of Java
 -- such as the Swing extensions -- are not implemented by the
 free GNU Classpath libraries, which the CACAO runtime uses.
