provisioning script broken?

[Ivan O'Donoghue]

After finally getting provisioning going for vvv, the provisioning script itself has a host of failures. 

Downloading of wordpress, for example, failed. It looks like a permissions issue. the /srv/www directory is owned by root and when I ssh in and run the curl command, it fails to commit the file. It works if I do sudo -i to change to root, or chmod 777, but there are other errors later - e.g. wp-cli core config fails because access is denied for the user wp which hasn't been set up . As a newbie this is making me tear my hair out.
