> Pig package does not include the jython jar within lib/ directory with the jar-all ant target but includes it in the "ant package" target. It should be including it in both targets as often, the build/ directory is excluded from packaging which is where ivy puts all the dependency jars while building under build/ivy/lib/Pig
> To reproduce:
> ant jar-all 
> rm -rf build/ 
> bin/pig
> grunt> register '/tmp/test.py' using jython as myfunction;
> If done prior to installing jython, here's the error one gets:
