Error on Generating docs

[alaabadran]

When trying to generate, i get the following error:
ERROR: Error: Command failed: /bin/sh -c /github/dox-app/node_modules/grunt-dox/node_modules/.bin/dox-foundation --source app/scripts/ --target docs --title "Test Documentation"

When i set the formatter value to dox-foundation as:
var formatter = 'dox-foundation';
instead of
var formatter = [doxPath, 'node_modules', '.bin', 'dox-foundation'].join(path.sep);
Things works fine.

Could you please look into this?

FYI, i am using Apple Macbook.
