   Thanks again for your scripts.  I did get them to work for LLVM 2.6
attached are the very minor changes.  In the end I added -arch to the
install-llvm and removed the flags from install-llvm-gcc.  Not sure
why this worked but now the Tutorial stuff seems to work.  Without
your scripts I don't think I would of gotten it built and running.
Thanks again!
