I think you may be correct about the mismatch. Starting again from  
scratch with a clean VTK build and a clean project build fixed the  
remaining issues.

Another possibility may have been that changes to paths in Xcode's  
Source Trees, i.e. for $(vtk-debug), don't seem to propagate to the  
open projects -  you have to close and reopen. I didn't realise this  
at the time, so the project may have been trying to link against the  
wrong build.

In any case, a fresh start using the system zlib resulted in a  
successful build of the application.

Thanks for you help,


Dan.
