LCD3 cape calibration

After long twigling with BB Black I managed to setup my application.
Now all work fine just the touchscreen isnt calibrated. It’s ok on center but too short in corners.
I had debian whezzy instaled.
I search the web and can’t find solution

xinput-calibrator doesn’t exists… (or I can’t find it)

sudo apt-get install xinput-calibrator
just fail.

some help?

it works in angstrom, but tkinter doesn’t work in angstrom…
