Bo,

I have following files on the pi :
/usr/lib/libpigpio.so
/usr/lib/libpigpiod_if2.so

Do you have these ? I'm running the latest raspbian-image 
(2016-05-27-raspbian-jessie.img).
You could also download the library from 
http://abyz.co.uk/rpi/pigpio/index.html and compile and install that.

To use the library, you need of course enable the gpio-server 
(raspi-config/advanced options). Or manually start it when you have an 
older (or different ?) OS-version.
