For a Mac system, Unix tools are not available by default. You will first need
to install Xcode from the Mac AppStore and then run the following command from
a terminal:

To install Unix tools, you can install "port" following the instructions at
https://www.macports.org . This will reside in /opt/local/bin/port for most
Mac installations.
-
- $ sudo /opt/local/bin/port install autoconf automake libtool
-
+```shell
+ sudo /opt/local/bin/port install autoconf automake libtool

Then follow the Unix instructions above.
