IMHO you have to make sure that the correct wx version is loaded.

So if we place an "import wx" into pyhoca-gui(.exe), we should make  
sure the correct wx.version is used. So "import wx" needs to be blown  
up to:

"""
try:
     import wxversion
     wxversion.select('2.9')
except: pass

try:
     import wxversion
     wxversion.select('2.8')
except: pass

import wx
"""

If that fixes the problem on Windows, I am happy with these extra  
lines in pyhoca-gui. (Please accompany those lines with a comment that  
explains, why the import occurs there, although the wx module is not  
used in pyhoca-gui(.exe) directly (but only in submodules).
