    build_helpers: Add Mint to the special case install list (#225)
    
    Really we shouldn't be installing to `dist-packages` like this, but I
    can't find any guidance on what a Python _application_ is supposed to do
    to integrate nicely with the Debian-style Python layout if it's not
    being packaged.
