_tkinter.so: undefined symbol: PyThread_acquire_lock

[Thomas Gagne]

'Ya know, I looked at threadmodule.c and didn't see a definition for
PyThread_acquire_lock.  I saw one for lock_PyThread_acquire_lock, but not the
former.

There's a comment in the source that reads:

"(PyThread_acquire_lock() is an obsolete synonym)" right below the code for
"lock_PyThread_acquire_lock()".  Are the 1.5.2 sources out-of-sync?
