I have been worried that I wouldn't be able to do Vpython on my
machine, because I had to install 64-bit Python for another package
that I needed for work.
My son found a good workaround for me:
arch -i386 python 4p90.py
(on some machines,
arch -32 python 4p90.py
)
This forces the 32-bit architecture, even though the 64-bit Python is
installed. (I don't use IDLE or the Vpython version of IDLE, so I
don't know whether they work this way or not.)
It might be worthwhile for other people dealing with the 32-bit Python
on the Mac problem to try playing with this. If it works generally,
it might be worth adding to the documentation.
