ino build command fails on rasberry pi

[Qualphey]

I have installed inotools on raspberry pi and now I'm trying to use it. But when I run ino build i get the following output:

Traceback (most recent call last):
  File "/usr/local/bin/ino", line 4, in <module>
    __import__('pkg_resources').run_script('ino==0.3.7', 'ino')

Did you have the arduino package installed before running this?
