[vtkusers] VTK_USE_MATLAB_MEX mac problem with libvtkGraphics

[Eric E. Monson]

Hey Jeff (and Tom),

Thanks, that at least gets it running. 

It seems like one of those things that shouldn't need to be done that way to work -- there should be some way to take care of it during the build instead -- but, unfortunately, I'm too ignorant to know the answer offhand.

Thanks for the quick reply and looking into it for me.
-Eric
