On Adafruit's tutorial...

http://learn.adafruit.com/drive-a-16x2-lcd-directly-with-a-raspberry-pi

... they recommend the package rpi.gpio.  I am not aware of a generic
GPIO scheme for desktop Linux distros since I don't think there's a
feasible way to do GPIO on the platform (except for parallel-port
banging on those machines that still have parallel ports).

Second that.
