Can't import setupV1 on Mingw (dupe?)

[Le Snelson]

This may be a duplicate as the list did not display my 1st attempt.

I installed peppy using pip in an Msys2, Mingw64 environment - python2.7

521 > pip install git+https://github.com/robmcmullen/peppy.git

Collecting git+https://github.com/robmcmullen/peppy.git

  Cloning https://github.com/robmcmullen/peppy.git to c:\users\le\appdata\local\temp\pip-tv6buo-build

Installing collected packages: peppy

  Running setup.py install for peppy

Successfully installed peppy-svn-devel

Result:

523 > peppy.bat

Traceback (most recent call last):

  File "D:\mingw64\bin\peppy.bat", line 20, in <module>

    import peppy.main

  File "D:/mingw64/lib/python2.7/site-packages/peppy/main.py", line 11, in <module>

    from wx.lib.pubsub import setupv1

ImportError: cannot import name setupv1

Any ideas about the different behavior from a normal Windoz installation.  Yes, it worked in that context.  No, that wasn't sufficient for me.
