Ian Wienand a85ce75d6b Pre-install pip/virtualenv packages ... If we're installing pip/virtualenv from source, we need to make sure we pre-install the packaged versions before the upstream versions. Otherwise, CI jobs later on that depend on packaged versions of pip/virtualenv can bring them in and overwrite the upstream versions we have installed, which leads to a heck of a mess and usually very confusing failures. I have also moved in a small hack from system-config:install_puppet.sh that we found was necessary when using pip versions from upstream. Note this is not as much of an issue on Debian/Ubuntu, as they keep their pip packages in a separate place to the system packages, so you don't have these overwite conflicts as much.
