We already have a working cvs, svn, git and mercurial (hg), for Haiku. Now we have a bzr built for Haiku, although it is untested at this time: http://ports-space.haiku-files.org//?directory=./&search=bzr If you have access to a bazaar repo and would like to kick this around and let us know how it's working that'd be great. If you have any issues with it let us know over at HaikuPorts -scottmc
