4.0.6 - dependence on pathlib2

[2sn]

Operating system: Fedora 30
wxPython version & source: pip (pypi)
Python version & source: 3.7.3, stock, self-built from source

Description of the problem:

pip install -U (pip install) does not appear to contain explicitly dependence on pathlib2. At least not for me. Could this please be added?

  Found existing installation: wxPython 4.0.4
    Uninstalling wxPython-4.0.4:
      Successfully uninstalled wxPython-4.0.4

    ----------------------------------------
  Rolling back uninstall of wxPython

The error message should not occur, pathlib2 should have been installed before as prerequisite.

This seems to have been fixed in 4.0.7 by #1241
