pyzmq 15.4 and python 3.5.2

It takes a little time to get the latest pyzmq installed.  So far, here is a list of things that I have done.
Note: This is on Ubuntu 16.04.

Preparation
curl -O https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
sudo python3 -m pip install cython

Download zeromq 4.1.5
http://zeromq.org/intro:get-the-software

Build zeromq 4.1.5
tar xf zeromq-4.1.5.tar.gzcd zeromq-4.1.5
./configure
make
sudo make install

Download pyzmq 15.4
https://github.com/zeromq/pyzmq

unzip pyzmq.zip

python3 setup.py configure --zmq=/usr/local

sudo python3 setup.py install

"""Simple example of publish/subscribe illustrating topics.

Publisher and subscriber can be started in any order, though if publisher
starts first, any messages sent before subscriber starts are lost.  More than
one subscriber can listen, and they can listen to  different topics.

Topic filtering is done simply on the start of the string, e.g. listening to
's' will catch 'sports...' and 'stocks'  while listening to 'w' is enough to
catch 'weather'.

Pretty much following the following two threads.
http://www.tonymacx86.com/threads/guide-lenovo-z50-70-using-clover-uefi-10-11.179520/
http://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Note:
1) Clover version 3625 is good.  Other versions may not boot.  This is the main lesson learned.
2) Do not add more than needed. 
3) Use MBR

Partition USB
diskutil list
diskutil partitionDisk /dev/disk1 2 MBR FAT32 "CLOVER EFI" 200Mi HFS+J "install_osx" R

Use Clover EFI 3625 install to install_osx

createinstallmedia to install_osx

BIOS enable UEFI first

Install and enjoy
