The HHVM role fails on provisioning with the error being that hhvm-fastcgi's dependency on hhvm >= 2.3.0 cannot be met. This happens even if hhvm 3.0.1 has been manually installed.
The cause appears to be that with HHVM 3.0, hhvm-fastcgi has been deprecated. The role probably needs to be rewritten to take the change into account.
