I'm using the Beaglebone and I had installed this software: http://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/installation the test works fine (webpage test) but when I'm trying to run my first program it doesn't recognize the library the mistake is:
import BBIO.GPIO as GPIO
File "<stdin>", line 1, in <module>
ImportError: No module named BBIO.GPIO
