title: How do I install wxPython on Mac OS X?
body: <p>I'd like to use wxPython on my Mac OS 10.7 (Lion) computer. (I'm a Tkinter refugee.) I upgraded from Python 2.7.1, then downloaded and installed wxPython2.8-osx-unicode-2.8.12.1-universal-py2.7.dmg. Here's what I get:</p>
  
  <pre><code> Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
   [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
   Type "copyright", "credits" or "license()" for more information.
   &gt;&gt;&gt; import wx
   Traceback (most recent call last):
