Hey, you cheated :). Your error message surely looked different than
Christian's.

I submitted a patch to the vtkGetDataRoot.m function to upstream two
weeks ago; this should take care of missing vtkdata packages in the
future.

Hmm, we could bump vktdata's "suggests" to "recommends" instead. And/or
apply the attached patch. This might be easier than pointing people to
READMEs.
