Why is this autogen.sh script failing?

I've downloaded [this](https://github.com/linuxmint/muffin) window manager from github and it has a autogen.sh script but it failed each time. I don't know what could happen or how to fix it: Output from ./autogen.sh: /usr/bin/gnome-autogen.sh checking for autoreconf >= 2.53... testing autoreconf... found 2.69 checking for glib-gettext >= 2.2.0... testing glib-gettextize... found 2.40.0 checking for intltool >= 0.25... testing intltoolize... found 0.50.2 checking for pkg-config >= 0.14.0... testing pkg-config... found 0.26 checking for gnome-doc-utils >= 0.4.2... testing gnome-doc-prepare... found 0.20.10 checking for gnome-common >= 2.3.0... testing gnome-doc-common... found 3.10.0 Checking for required M4 macros...
