You should always see this warning.  The msys2 wxPython release is 3.0.2
and the wxWidgets release is 3.0.4 which causes the version mismatch.
Again, AFAIK, there this does not create any issues other than the fact
that wxPython is dead and has been replaced with wxPhoenix.  wxPhoenix
is wxPython for Python 3.  Unfortunately, the wxPython folks broke the
build scripts for wxPhoenix which means that you cannot build it on
msys2.  This *is* going to be a problem in the not too distant future
for windows users unless we either fix the wxPhoenix build scripts for
msys2 or switch to the free version of msvc to create windows builds.  I
prefer the former but we may not have any choice depending on manpower.

These are known issues with the code generated by SWIG to build the
Python scripting module.  AFAIK, they do not present any issues.
