ImportError: No module named lib2to3.pgen2.parse

[Sevyx]

Branch/Commit: Master OS: armv5tel - python 2.7.14 What you did: First had a different error then decided to update it with the following command:

git remote set-url origin https://github.com/SickRage/SickRage.git
git fetch origin
git checkout master
git branch -u origin/master
git reset --hard origin/master
git pull

Even tried python 3.5 but didnt fix it either so switch back to python 2.7.14

What happened: Cant start up pymedusa after the update 2 days ago. Tried trouble shooting myself but gave up since my knowledge of python is limited.

What you expected: a working pymedusa

@medariox Why do we need past.builtins.cmp? Isn't cmp available for both Python 2 and 3?

[medariox]

Gone in Python 3 https://docs.python.org/3.0/whatsnew/3.0.html#ordering-comparisons

Same happened on Libreelec distro. Python 2.7 on Libreelec is missing the lib2to3 module. So, last Medusa update can't start anymore on this system.
