CA.all problem

Hi, Using the provided script "CA.all", trying to create self-signed certs on a new freeradius box and running into a missing serial file problem. Executing the commands in the script line-by-line shows that the command "openssl ca -policy policy_anything -out newcert.pem -passin pass:whatever -key whatever -extensions xpserver_ext -extfile xpextensions -infiles newreq.pem" is what is looking for the file "./demoCA/serial" which does not exist. I think it is normally created during "CA.pl -newca" but this doesn't appear to happen with the script's command of "echo "newreq.pem" | /usr/local/ssl/misc/CA.pl -newca". I'm using OpenSSL version 0.9.8e. Anyone have this experience? Thanks!
