undefined symbol: PyThread_acquire_lock

[Thomas Gagne]

This is driving me NUTS.  I'm pretty sure I've recompiled everything I could,
tried configuring Pything with and without "--with-threads", used both
Tools/idle (0.4) and the latest version, 0.5, without success.  Does anyone
know why I would be getting this error???
