  Haven't used xruby myself but com.xruby.runtime.lang.RubyProgram
seems from xruby and not from the generated code. Maybe you need xruby
in your classpath? Putting the needed jars on the environment variable
CLASSPATH or using java -classpath argument might help. Try something
like 'java -classpath /path/to/xruby.jar -jar test.jar'

You can read http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/classpath.html
or http://java.sun.com/j2se/1.5.0/docs/tooldocs/windows/classpath.html
for more information on how to set up the classpath.
