_tkinter.so: undefined symbol: PyThread_acquire_lock

[Thomas Gagne]

Ok, I discovered pything1.5 was already installed on my RHAT 6.2 system and
got the above error (traceback below).  I got the same result after rebuilding
it with

./configure --prefix=/usr --with-threads
make
make install (as root)

tgagne:/home/tgagne/tmp/idle-0.5 ./idle.py
Traceback (innermost last):
