brew install docker docker-machine
brew cask install virtualbox
-> need password
-> possibly need to address System Preference setting

# first time
docker-machine create --driver virtualbox default

#subsequently
docker-machine start

#then
docker-machine env default
eval "$(docker-machine env default)"

(miniconda->miniconda3)

docker run -t -i -p 8888:8888 continuumio/miniconda3 /bin/bash

then

conda config --add channels conda-forge
conda install cling
conda install libgcc
#conda install emacs
conda install llvmdev=5.0.0

cd /opt/conda/bin/
ls x86_64* | awk '{print "ln -s "$1 " " $1}' | awk '{t=$4; sub(/_cos6/,"",t); print $1,$2,$3,t}' > go
source go

#now cling works.

#problem - llvm is not installed...
