Error when provisioning install script returning "7" instead of "0"

[dane-harnett]

I'm getting this error:

err: /Stage[rvm-install]/Rvm::System/Exec[system-rvm]/returns: change from notrun to 0 failed: bash -c '/usr/bin/curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer -o /tmp/rvm-installer && chmod +x /tmp/rvm-installer && rvm_bin_path=/usr/local/rvm/bin rvm_man_path=/usr/local/rvm/man /tmp/rvm-installer --version 1.20.12 && rm /tmp/rvm-installer' returned 7 instead of one of [0] at /tmp/vagrant-puppet/modules-0/rvm/manifests/system.pp:19

Thought it could be due to proxy however these are all correctly set as far as I can tell.
