[vtkusers] Building VTK on mac OS10.3.2

[David Bernstein]

Hi All, I'm trying to build vtk 4.2.3 on mac OS 10.2.3.  After doing 
cmake -i and entering
what I *think* are reasonable values and doing make, the build fails 
(see below).

Any ideas on what's going wrong?

I chose the cocoa option and am not building shared libraries, if that  
helps.

Thanks,
Dave Bernstein
