Same problem on Arch Linux where wxPython 2.8 package requires wxPython
3 package. Thus one can't have wxPython 2.8 installed alone, while GRASS
wxgui defaults to wxPython 3 in case both 3 and 2.8 are installed.

Question to GRASS team: would there be any problem with adding the above
wxversion selector to all wxgui code that is not comaptible with
wxPython 3? Further in the thread Glynn suggested:
