jline and commons-lang - building 0.8.0 download

[Jeremy Hanna]

Is there a standard way to get jline and commons-lang into pig?  I work around 
by copying them into my build/ivy/lib/Pig directory but didn't know if there 
was a simpler way I was just overlooking.  Otherwise I get an UNRESOLVED 
DEPENDENCIES errors for those two libs when I try to build pig 0.8.0 from 
source.
