Building KiCad: wxPython dependency

Hello. I’m trying to build KiCad from source and I’m a bit confused about versioning of wxWidgets and wxPython. As been said in this conversation (https://lists.launchpad.net/kicad-developers/msg16783.html) major and minor versions of wxWidgets and wxPython should be the same. So, I’ve successfully installed latest stable wxWidgets - 3.0.3. But this page (https://pypi.org/project/wxPython/#history) doesn’t mension any 3.0.x wxPython versions at all. All we have is legacy wxPython 2.9 and new wxPython/Phoenix 4.0.0. So, which one should I use? Or I’d have to build it myself somehow?

OK, as it always happens, I found a github repository of wxPython 3.0 15 minutes after the question here (https://github.com/wxWidgets/wxPython). Here’s my experience if someone is interested.
Unfortunately, I got ahead of myself and installed wxWidgets from source without wxPython. It seems that build script in this repository can build and install wxWidgets and wxPython at the same time. Luckily this script has option that allows to build wxPython only, so the build command was python build-wxpython.py --install --no_wxbuild. After the installation I tried import wx in python terminal to test it out, but got an missing _core_ error, which was fixed by reboot.
However, despite of working hello_world example kicad building script tries to find wxversion module and fails. But that’s another question.
