Hi, I have just restarted building Debian/Ubuntu OpenVPN packages for the feat_allmerged branch of openvpn-testing.git for my private use. If you want to test them, feel free to have a look at https://launchpad.net/~berni/+archive/ipv6 . There are up-to-date versions for Ubuntu Karmic and Ubuntu Lucid available. The lucid package works just fine on Debian Squeeze.
I don't have binaries for older Ubuntu versions and for Debian Lenny at the moment, because my package relies on new features of dh7. It should be possible to create one with a bit of work if there is demand (I don't run OpenVPN on Lenny anywhere). I will try to automate rebuilding packages on git updates if someone is interested in them. Best Regards, Bernhard
