Problem setting up git diff

I tried to set up Changes.app with git using the instructions on the Changes Wiki[1] and have a script set up as described there:


#!/bin/sh
[ $# -eq 7 ] && /usr/bin/env chdiff --wait "$2" "$5"


I have also set the git diff.external using git config --global to use that script but whenever I run "git diff" I get:


external diff died, stopping at [file]


I have chdiff installed through the Changes menu and launching Changes through chdiff works without problems. I am using git v1.6.3.3 and the latest Changes app.

Any ideas?
