No touch on official 7" Touchdisplay

[Tigress]

I haven't got a touch screen so I can't test this but in a forum I read: Installing "Two Finger Touch for Raspberry Pi Official Touchscreen" can work.

Code:

git clone https://github.com/pimoroni/raspberry-pi-two-finger-touch.git
cd raspberry-pi-two-finger-touch
./install.sh

Can someone test this?

On latest Wheezy with Foundation 7" display
, successfully did the clone but fails at ./install.sh with "/dev/twofingtouch: No such file or directory"   Any thoughts?
