The shebang line is (optionally) the first line of a Unix script,
starting with #!. It tells the OS what interpreter to use to run the
script, and what arguments to pass to it. In this case, you should
check to see which ruby interpreter version is named in the #! line of
rake (which you can find by typing which rake).
