In reference to Steve's question, VTK is regularly tested with several
OS X compilers and it shouldn't really matter which one you use, as
long as you are using VTK 5.8 or later.  All of gcc-4.0, gcc-4.2,
llvm-gcc-4.2, and clang will provide similar performance, as far as I
understand it.  Just use the default compiler that comes with
whichever version of XCode you are using.
