Sorry, had to vent. I have NEVER been able to get a wxPython program to work correctly. IN FACT, a simple dumb hello world program doesn't work.

This script:

$ cat hello.py
#!/usr/bin/python
#
import wx
app = wx.PySimpleApp()
frame = wx.Frame(None, -1, "Hello World")
frame.Show(1)
app.MainLoop()

Produces...

python hello.py
Traceback (most recent call last):
  File "hello.py", line 3, in ?
    import wx
ImportError: No module named wx

GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
