Building bitcoin with gitian-builder

build-bitcoin.sh

    # First run:
    apt-get install apt-cacher python-vm-builder
    vi /etc/default/apt-cacher # ensure autostart is enabled
    sudo service apt-cacher start
    # Note that apt-cacher caused some problems for me, you can also try apt-cacher-ng, making sure to set the listen address to 127.0.0.1 (which it for some reason doesn't do if you have IPv6 in some cases)
