gnutar not installed by default on Mac OS X, and when it is, it's "gtar" #11

Maybe a more friendly message could be helpful, or something in the docs, to tell Mac users to run brew install gnu-tar.

I don't know the history of line 107 ([[ $(uname) == "Darwin" ]] && TARCMD=gnutar) (maybe macports?), but when it is installed, it is linked as gtar

History for this line is in 9c3dbd639d642a699a5621c676616c6af99eab63. Apparently Mac OS X used to ship with gnutar installed by default but no longer does. This should probably be fixed to explicitly test for support of the --concatenate option and complain if it's not available, rather than trying to do operating system detection and assuming the correct kind of tar is installed.
