I didn't realize that I had a fix for these warnings in my source.  
Cocoa applications require that a NSAutoreleasePool is established to  
handle resource management. Any Debug build will yield many of these  
errors unless using some other wrapper to drive an executable. The  
Dashboard shows these errors at  
<http://www.vtk.org/Testing/Sites/krondor.kitware/Darwin-c++-cocoa/ 
20040213-0300-Nightly/Results/__Rendering_Testing_Tcl_CamBlur- 
image.html>. My fix involved creating an AutoreleasePool for  
vtkCocoaRenderWindow. The pool is initialized and cleaned up as needed.  
No fix for the CamBlur failure yet (it's using single-buffer OpenGL,  
and that doesn't really exist on MacOS X), but at least the explosion  
of _NSAutoreleaseNoPool errors go away.
