It's not going to work without the "import os" - you need to add both lines, the "import" at the top (line 25) and the second line at either line 43 or line 58.

However if you've got it working using an absolute path, timker should be able to fix it properly so that the addon works on all distributions (OpenELEC, Raspbmc, OSMC, Xbian, Raspbian etc.)
