How to install bzr-svn?

[Josef Wolf]

Hello,

I am trying to follow the instructions on

  http://wiki.bazaar.canonical.com/BzrForeignBranches/Subversion

so I do

  mkdir -p ~/.bazaar/plugins
  cd ~/.bazaar/plugins
  bzr checkout http://people.samba.org/bzr/jelmer/bzr-svn/0.6 bzr_svn

  cd ~/projects
  bzr co https://my.server/repos/project
  No module named svn
  Unable to load plugin 'bzr_svn' from '/home/jw/.bazaar/plugins'
  HTTPS my.server, Realm: 'Some Subversion Repository' username: jw
  HTTPS jw at my.server, Realm: 'Some Subversion Repository' password:
  HTTPS my.server, Realm: 'Some Subversion Repository' username: jw
  HTTPS jw at my.server, Realm: 'Some Subversion Repository' password:
  bzr: ERROR: Not a branch: "https://my.server/repos/project/".

  bzr co https://my.server/repos/project/trunk
  No module named svn
  Unable to load plugin 'bzr_svn' from '/home/jw/.bazaar/plugins'
  HTTPS my.server, Realm: 'Some Subversion Repository' username: jw
