python environment returns error "I can't find file `document.py.out'" using texlipse in Eclipse

I'm tinkering with adding Python functionality to LaTeX, and I prefer to use Eclipse as my editor. I have tried a simple code:

\documentclass{article}

\usepackage{python}

\begin{document}   

\begin{python}
print 'Hello World'
\end{python}

\end{document}

I get the following error:

I am running Mac OSX 10.10.5. It seems like I should be adding some parameters to the builder but I'm not sure what. Thanks in advance for the assistance.
