Looks like your machine is missing some dependencies, for Ubuntu you need to install: `sudo apt-get install \ build-essential pkg-config libc6-dev m4 g++-multilib \ autoconf libtool ncurses-dev unzip git python python-zmq \ zlib1g-dev wget curl bsdmainutils automake` follow the guide here: [User Guide — Zcash Documentation 5.2.0 documentation](https://zcash.readthedocs.io/en/latest/rtd_pages/user_guide.html)
