py36-flake8 3.3.0_1: requirement on pyflakes <1.6.0 >=1.5.0 not noted in port dependencies

[obriencj (Christopher O'Brien)]

After an update to pyflakes, flake8 no longer functions as it has a pkg_resources dependency on pyflakes 1.5

Running flake8 results in a traceback, with the pertinent line being

pkg_resources.DistributionNotFound: The 'pyflakes<1.6.0,>=1.5.0' distribution was not found and is required by flake8

However, this dependency is not reflected in the port, as the upgrade of pyflakes happened without complaint.

Relevant installed ports

  py36-flake8 @3.3.0_1 (active)
  py36-pyflakes @1.6.0_0 (active)
  flake8_select @0.1_0 (active)
  pyflakes_select @0.1_0 (active)
