1 - build and install lib/openvpn-down-root.so plugin (see --plugin option in
the man page) and README.openvpn-down-root
2 - match rc.d filename as printed post install in pkg-message to actual file
name on newer systems (which use openvpn rather than openvpn.sh)
Reported by: Jean-Baptiste Quenot (Bcc'd)
The maintainer wishes to thank Jean-Baptiste for his report and patience.
3 - add a pkg-req script to prevent installation of 6.1 packages on older
machines, which is a frequent source of "rc.d script doesn't work"
