Puppet redis exec and install

redis exec

# The case statment is running too late, it needs to run earlier

  }

In the output, notice that the message "Installing redis from /tmp/" appears before the message "Installing redhat redis from /tmp'.
Also, I suspect that the reason the package is failing is because it can't find the location of the rpm
