And.... not quite.

arch -i386 idle2.7 

now works!  But it appears to start a 64 bit version of Python in a 32 bit IDE, because when I

import wx

it gives me the "wrong arch" message.
How do I force 32 bit idle2.7 to start 32 bit python? 
Or for that matter, shouldn't I be able to get 64 bit idle to start 32 bit python? That probably makes a little more sense.
