It's not as simple as that. The ~bzr PPAs typically target being able to
be used on an otherwise stock Ubuntu system. With that in mind, there's
no place to obtain a Subversion >= 1.5 on hardy to link against.

There's a Subversion 1.5.1 in hardy-backports, but it would break
precedent to mandate that people enable the backports pocket to be able
to install bzr-svn on hardy from the ~bzr PPAs.

Likewise if we were to depend on any other Subversion in another PPA.

And it doesn't feel particularly logical for the ~bzr PPA to distribute
a version of the subversion package, either.

If hardy was less completely obsolete, I'd be inclined to try harder to
find a solution, but I'm unsure it merits the effort to do anything
about this for a LTS-minus-two release, that reached desktop EOL over a
year ago.
