[vtkusers] SimpleCocoaVTK problems

[Corrie]

Now I'm really confused.  I've tried to edit the CMAKE_CXX_COMPILER  
and CMAKE_C_COMPILER's in cmakecache.txt to g++-4.0 and gcc-4.0,  
respectively.  Then, after I save the file and cmake it a couple of  
times, it (cmakecache.txt) has reverted to having 3.3's in those  
fields.  Any idea why CMake can't get this to change?   I even tried  
putting "powerpc-apple-darwin8-gcc-4.0.1" in there and it still  
reverted back to gcc-3.3 in the cmakecache.txt file.   All this  
despite the fact when I ask gcc -v, I get "gcc version 4.0.1 (Apple  
Computer, Inc. build 5367)" in response.   How can I exorcise this  
ghost in the machine?
