Yes. With the PRIVATE flag set, some of the bundles would not be able to 
find the symbols in the other bundles. VTK is a cross-platform library, 
and it (sort of) assumes that the Python extensions are libraries.
This is true for ELF systems:

Can we build the Python extensions as dynamic libraries instead of 
bundles? I think I saw several NeXT functions that might be useful for 
doing the loads (NSAddImage and company).

There may be problems, though. The note from Fink claims that dynamic 
libraries cannot be unloaded. Any thoughts? I am clueless about these 
NeXT-ish things...

Now, this is a bit off-topic. Is there a way to link a bundle to another 
bundle? If there's a way to tell bundle B to go look up some symbols in 
bundle A, it would really help. I think that there is none, but I want 
to pass this question to the list just to make sure.
