Can't install, not finding specified version of zeromq4 #8

    Configuring zeromq4-haskell-0.7.0...
    Cabal-simple_mPHDZzAJ_2.4.0.1_ghc-8.6.4: The pkg-config package 'libzmq'
    version >=4.0 && <5.0 is required but it could not be found.

I'm installing on Ubuntu 18.04. My version of Stack is 1.9.3, which stack upgrade tells me is the latest. I was running these four steps from the README:

git clone https://github.com/litxio/ptghci
cd ptghci
pip3 install -r pybits/requirements.txt
stack install

The error happened in the fourth step.

You'll need to install ZeroMQ and other dependencies. On Ubuntu the below command should do the trick:

apt-get install pkg-config libpcre3-dev libzmq3-dev python3-dev python3-pip
