For anyone who cares (and maybe we should take this off the mailing list) I updated the now called MathBlotter to use Maven to construct the JJTree files. It *should* compile, but fails on some tests. It will run though and render equations in pretty LaTeX output. https://github.com/wspeirs/MathBlotter
Again, any help would be greatly appreciated...
