[vtkusers] SimpleCocoaVTK problems

[Mike Jackson]

Corrie,
   Lets start over. What we need to do is match the compilers for both VTk and SimpleCocoa.

 So.. 
   Go into the directory where vtk was built. Blow everything away.
   Go into the directory where SimpleCocoa was built. Blow it all away.

now from a terminal type:
sudo gcc_select 4.0 -force

This will make the system compiler be the latest 4.x from Apple.

Now Rebuild VTK
Now Rebuild Simplecocoa.

Then let's see what happens after that.

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?
