Comment 9 for bug 1612554

I didn't install any specific version, since it was included in the duplicity tarball:

$ tar tf duplicity-0.7.09.tar.gz | grep -i rsync
duplicity-0.7.09/duplicity/_librsyncmodule.c
duplicity-0.7.09/duplicity/librsync.py
duplicity-0.7.09/duplicity/backends/rsyncbackend.py

$ pip list
boto (2.42.0)
duplicity (0.7.9)
lockfile (0.12.2)
pip (8.1.2)
setuptools (25.2.0)
wheel (0.29.0)
