Christos; I found a new 1.0 release in unstable for Debian.

Ubuntu is the one causing me problems now. It's still 0.90 and according
to the error message 0.92+ is needed.

### bzr branch $TRUNKURL /src/bzr/trunk
bzr: ERROR: Unknown branch format: 'Bazaar pack repository format 1
(needs bzr 0.92)\n'

### bzr --version
Bazaar (bzr) 0.90.0

Please use Squid 2.6STABLE17 or 3.0STABLE1.
There are serious security advisories out on all earlier releases.
