I checked the one char change on my system thoroughly. I looked around 
on some forums and NGs 4 months ago, and found no one even had a simple 
"compiled program" available to even demonstrate some simple example.

I would think there are some small time and big time Python players who 
sell executable versions of their programs for profit?

disutils. Sounds familiar. I'm pretty sure I was using Py2Exe, and 
disutils might have been part of it.

So how does one keep a non-Python user in lock step with my setup, so 
these problems don't arise? I don't even want to think about having him 
uninstall and re-install. :-) Although maybe he could do it without 
making matters worse.
