.pyo's without .pyc's?

M.-A. Lemburg:
 |Looks like you have setup PYTHONPATH to point to some old
 |extensions.py file (the compiled versions seemed to be ok).

It doesn't appear this is the case (please see below).

 |Try "python -vv" to have a look at the path scanning Python
 |does on startup.

I've attached the two different search outputs below.  As you can see, even
with -O, it's searching .pyc files even when .pyo is specified.  As far as
I've heard, this is incorrect behavior.

 |Running Python with .pyo files only works just fine if you
 |remember to always use the -O flag on the command line.

I hope it can be made to work that way, but it doesn't seem to.

 |For minimalist Python installs, you could also check out the
 |mxCGIPython project:
 |
 |	http://starship.skyport.net/~lemburg/mxCGIPython.html
 |
 |It's Python wrapped into a single file (with the standard
 |lib compiled with -O BTW).

Alas, I need Tkinter compiled in and IIRC this doesn't work well with Tk
yet.

Thanks,
