I don't know the APIs you're discussing, so this comment is coming mostly from ignorance, but: are you talking about requiring OpenMP to build VTK?  Clang has only very recently added OpenMP support, and IIRC it's not complete.  Also, last I checked, Apple's fork of clang doesn't support it at all.

Cheers,
