Title:
  Python 3 is missing a standard directory from the module search path

Bug description:
  Running Ubuntu MATE 17.04.

  Python 3 has multiple directories for installed modules. The paths for
  system packages (/usr/lib/) are all correctly added to sys.path, but
  one of the paths for user installed packages is missing.

  The path /usr/local/lib/python3/ does not get added to sys.path. It's
  counterpart for system packages exists, and the python3.5/ or
  python3.6/ user paths are properly added to sys.path. Though it does
  not exist by default, the equivalent paths in ~/.local/ are also added
  when the directories exist.

  This is causing problems for the NTPsec project, as python's distutils
  module tells our installer to place python modules under
  /usr/local/lib/python3/ where python cannot see them. So far attempts
  to work around this result in either very brittle build scripts, or
  require the user to modify their PYTHONPATH.

  My understanding is that python search paths are determined by the
  distribution.
