Comment 4 for bug 79439

According to the news page at SixXS all old versions where deprecated when 2007.01.07 was released, that is probably the problem there.

But fortunately the version from the download page simply works.
Just use a extra apt-repository in /etc/apt/sources.list and done ;)

It would be great though if Ubuntu also had this new version so that Ubuntu is up to speed with the rest of the world.
