kodi-send claims “No module named xbmcclient”

Hi there,
I run Archlinux on my laptop and my desktop. I thought that the systems are both the same.

With these computers, I controll my kodi-openelec-boxes using kodi-send.

For example, I change to a specific user profile using

Code:
kodi-send --host=192.168.0.160 --port=9777 --action="LoadProfile(Master user)"

Or I update my videos

Code:
kodi-send --host=192.168.0.160 --port=9777 --action="UpdateLibrary(video)"

So, my problem is:
While everything is fine on my desktop, my laptop starts giving me the following error when I try to use kodi-send:

Code:
Traceback (most recent call last):
  File "/sbin/kodi-send", line 29, in <module>
    from xbmcclient import *
ImportError: No module named xbmcclient

Could anybody please give me a hint on how to fix that?

Greetings from Germany
Joe
