First I had to install python-setuptools: sudo apt-get install -y python-setuptools

Now I need to install wheel: pip install wheel

It would be good if the installation script installed all of these missing dependencies instead of failing.

Looks like one more dependency is missing. I am now installing it: sudo apt-get install gcc-arm-linux-gnueabihf
