[Zope] probable python version problem

[Ted holden]

Does anybody have the latest thinking on the following error message:

ImportError: 	
/home/bear/Zope-2.6.2-linux2-x86/lib/python/Products/instantindex/_iindexpymodule.so: 
undefined symbol: PyType_IsSubtype


This occurs when trying to load a .so file created with swig, which works well 
enough from a normal python/pygtk application.  

>From what I gather doing searches on the problem, it would probably go away if 
I were to recompile the .so file against python 2.1, but that's sort of like 
heading in the wrong direction.  I'd appreciate hearing from anybody with a 
better solution.
