Snow Leopard Cursor Keys broken.

[Nicholas Cole]

Dear List,

I'm having a strange curses problem on Mac OS 10.6.3.  If I use the
system provided python, curses applications do not correctly interpret
arrow keys (I've tried both with xterm and with Terminal.app, so I
don't think it is a terminal problem).  If I use the version of python
I've installed from fink, everything works as expected.

This is definitely a 10.6.3 problem.  When I found the problem on my
Desktop machine, I tested 10.6.2 on my laptop and it worked fine.
Upgrading to 10.6.3 broke the cursor keys in exactly the same way.

I've attached code that demonstrates the problem.  On 10.6.2 the left
arrow key produces "KEY_LEFT".  On 10.6.3 it produces "D"

Best wishes,

Nicholas
