Howto: Install pydbus for python3.6 on Centos EL7

Installing pydbus on Centos EL7 for python3.6 doesn't follow the usual steps. Because of the goals of Centos, users in production environments prefer to enable as few repositories as possible. Python3.6 has to be installed from the ius repository, while none of the 3.4 'native' packages are loaded. This uses bleeding edge fc26 versions (as of this writing, 2/17) of the related packages, including glib2. I advise using the latest available. Consider using 3.6 when deployment is not expected until 2018 (estimate).

Here are the steps as of 2/17 to install pydbus for python3.6 on Centos EL7 for x86_64:

After clean install, as root:

yum install https://centos7.iuscommunity.org/ius-release.rpm
yum upgrade
yum remove python3.4*   #just in case
yum install python36u*
mkdir ~/p36;cd ~/p36
wget https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/Packages/p/python3-gobject-3.22.0-3.fc26.x86_64.rpm
