gitscm: Can't connect to git repo

For the root user the path was already ok. I have added /opt/rfw/bin to the path in /etc/profile, but this doesn't change anything.

Here is a full log to demonstrate the problem:

quattro:~ ledermann$ ssh root@readynas
root@readynas's password:

Cloning into repo...
root@readynas's password: 
bash: line 1: git-upload-pack: command not found

Hope this helps for debugging. Maybe I'm doing something wrong.
