An error occured within the child DocPad instance: exited with a non-zero status code

Hi @axyz ,

Trying to install the Zurb-Foundation SASS skeleton but when I run "docpad run" I get this:

info: DocPad listening to http://0.0.0.0:9778/ on directory /home/user/project/docpad/out
info: LiveReload listening to new socket on channel /docpad-livereload
Performing renderFiles (pass 1) at 2/5 40% ===================------------------------------

it stays on 40% and that's all.
Any idea what causes it?
