Skill level (at least the following; tell us if you have a paper-specific skill):
    I can build complex software like GCC and the Linux kernel

Sequence of steps to build:

Detailed evaluation:

    Setup the SCALA_HOME variable, and add scala and scalac to the PATH variable
    untar the -src directory; cd into it, and run the make.sh.  Program
    successfully builds. 

Running: 

    I was however, unable to get this to run. Using the examples and the run.sh 
    provided in the -bin tarball. The first bug I encountered could be fixed by 
    correctly specifying the java_runtime_dir in the wala.properties:  
    
        lib/wala/dat/wala.properties

   I stopped pursuit at this point however.
