Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.10
Ubuntu 8.04
Ubuntu 6.06

After a standard system update you need to restart any applications that
use Subversion, such as Apache when using mod_dav_svn, to make all the
necessary changes.
