xcb.xproto not found

[GoogleCodeExporter]

I use pytyle2 on Xfce 4.8. With my external monitor plugged in, I get

~$ pytyle2 &
[1] 3186
~$ Traceback (most recent call last):
  File "/usr/local/bin/pytyle2", line 23, in <module>
    import xcb.xproto
ImportError: No module named xcb.xproto

[1]+  Exit 1                  pytyle2

Installing xcb-proto and python-xcbgen doesn't help. In my display settings, 
only my external monitor is activated.

It works again after I installed python-xpyb.
