I happened to fix that this morning:

It isn't very hard to do updates if you use an approach like
that I use for HDF5:

  http://vtk.org/gitweb?p=VTK.git;a=blob;f=Utilities/vtkhdf5/README-VTK.txt;hb=dfa8d922

Basically the original 3rd party code is kept unmodified in
a special branch and merged into VTK's tree.  Fixes to it
for our dashboard can be committed directly like any other
changes.  Later when the 3rd party code is updated, the new
version can be committed on the special branch and merged
again.  That way we merge the two paths of changes instead
of overwriting our version with theirs.
