Minor setup.py bug

[Mark Livingstone]

Hi Robin,

I have noticed a minor bug with wxPython/setup.py --help-commands

When you run it, it firstly does the wx-config / module preparation  
stuff meaning you are forced to run it su/sudo  which is a minor  
inconvenience. Having done that, it displays the help information  
three times (which is a waste of bits and photons and doubtless  
causing global warming ;-P )

Cheers,
