Ian Wienand 7a962e9d1c Skip python3-virtualenv on <= trusty ... If DIB_PYTHON_VERSION is < 3 on the !redhat path, that means we're on an older platform that may not have python3-virtualenv packages. Skip install. Ensure the order of operations happens by forcing the installs Also add a note about limited platform support (patches welcome :) Change-Id: I18412767f0ebf946d557a0a126285369e96af159		2017-04-12 06:36:20 +10:00
