In version 0.6.23 of duplicity, concurrency support was added, which introduced dependency on python-lockfile (see last line of changelog for version 0.6.23). Current version of ebuild doesn't state this dependency, so duplicity fails to run. Reproducible: Always Steps to Reproduce: 1. Run duplicity with any key (--version). Actual Results: Traceback (most recent call last): File "/usr/lib/python-exec/python2.7/duplicity", line 34, in <module> from lockfile import FileLock ImportError: No module named lockfile Expected Results: Duplicity should run as usual (output version and exit). emerge --info output: Portage 2.2.7 (default/linux/amd64/13.0, gcc-4.7.3, glibc-2.17, 3.12.4-pf-terminus x86_64)
