Problem w/Tkinter on 2.5 (Panther)

[w chun]

i've built a Python 2.5a0 interpreter on my iBook using gcc 3.3-1666
using the tarball from last nite...

$ uname -a
Darwin myMac.local 7.9.0 Darwin Kernel Version 7.9.0: Wed Mar 30
20:11:17 PST 2005; root:xnu/xnu-517.12.7.obj~1/RELEASE_PPC  Power

$
$ python
Python 2.5a0 (trunk, Mar 28 2006, 02:53:21)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> ^D

it has a particular symptom with Tkinter where if i run the
interactive interpreter, "import Tkinter", etc., things work great...
i can bring up and create Tk objects which work as expected using
XDarwin 1.3.0/XFree86 4.4.0, BUT when i try to run anything as a
script, even the 1-liner: "import _tkinter", it bombs out with a Bus
Error.  here is the output in GDB:

$ gdb /usr/local/bin/python2.5

has anyone else seen this error before?  the script (obviously) works
using earlier versions of Python.  i have Tcl/Tk 8.4 on my system and
have T{CL,K}_LIBRARY pointed at the right place(s) when i built my 2.5
interpreter.

thanks,
