tslib not working.

I built Qt4 from source with tslib support using -qt-mouse-tslib in the configuration options. I am able to run qt applications just fine but the touch screen isn't working.
How do i make sure i have tslib installed? I tried apt-get install tslib-bin and get the error "Unable to locate package tslib-bin". How do I install tslib?

also when i trun ts-calibrate i get “command not found”. Does this mean i dont have tslib installed?

google is always your best resource concerning packages. Then once you have established the package name, apt-cache search <package_name> is how one finds out if it exists for armhf.
