Rawhide version Spec needs BuildRequires: openssl-devel (I haven't tested to see that this is all that's needed as I'm going to finally make my hostname fully qualified and reboot. The postfix package won't build without a fully qualified hostname. I don't know what the minimum ssl version is.) I suspect that it might need "Requires: openssl" to run, but I don't know.
