That looks like a different problem.

If you check your VTK and ITK source trees for files with the name 'mangle' you'll find:

vtk_tiff_mangle.h
itk_tiff_mangle.h

They use preprocessor magic to change the symbol names of libTIFF functions to prevent the exact problem you are seeing.  I suspect something is missing from one of both of those files.  If you find it, a patch would be nice!

Cheers,
