Maybe I misunderstand, but this is what we want. We need to know that  
the default version of wx is at or above 2.8.1. So it doesn't matter  
if you have 2.6 and 2.8.1, if 2.6 is your default,

import wx
wx.version()

should say that 2.6 is running, which is the wrong version. This  
should generate an error out of CheckForWx().
