wxversion doesn't *check* for a particular version, it *chooses* a
particular version.

If you use wxversion.select(), you only need to have that particular
version installed.

OTOH, if you "import wx" without using wxversion.select(), then check
wx.version(), the desired version not only needs to be installed, it
also needs to be the default version (i.e. installed as "wx").

So, if you have e.g. both 2.6 and 2.8, and "wx" is 2.6, the code will
fail without the use of wxversion.select().
