Answer 1

"Cannot find autoconf" - Install autoconf and retry.

sudo port install autoconf but you need Xcode and MacPorts as far as I know.

Answer 2

You can also install autoconf through homebrew. Just run

brew install autoconf

And all will work

Answer 3

For me, I had not agreed to the Xcode license :-

$ sudo /usr/bin/m4 --version


You have not agreed to the Xcode license agreements. You must agree to both license agreements below in order to use Xcode.
