        That's all for me.  Next check out the compiled version with:

                  vim72/src/vim --version 

        and you should see that all patches were applied. 
        Next copy vim, vimtutor, and any other binaries you want to 
        keep from this deeply moving experience to a directory in your 
        path, and have fun with some vanilla vim!
