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.
