Howto: Install pydbus in Anaconda or Conda python v3.6

The Anaconda / Conda suite can install and maintain several different python environments, including python3.6, in a portable user directory tree, all without needing elevated privileges. Getting pydbus running inside a 'conda' environment takes a few more steps because of the many system libraries pydbus requires. These instructions will add the necessary system libraries pydbus needs to a python3.6 environment, also without requiring elevated privileges.

These instructions are for the 'rpm' using of the Linux distributions, and tested on Centos EL7, which should also work for the Fedora/ RedHat / similar distros. The same ideas should work as well for the other packaging systems.

Download then create an Anaconda environment in a user directory using the Anaconda instructions. In this case:

bash Anaconda3-4.3.0-Linux-x86_64.sh
; accept defaults.

cd ~/anaconda3/bin
conda update conda
conda update anaconda
anaconda-navigator
;Choose: Environments;Create;name py36 environment python version 3.6;exit
;It isn't necessary to use the Anaconda gui, but it installs the most used packages quickly.
source activate py36
pip install -U pip
;now a generic python 3.6 environment is ready.
pip install pydbus
;now fetch and install the support libraries
mkdir ~/p36extras;cd ~/p36extras
