In general, you should not be installing anything into /usr/bin or /usr/lib; the contents of those directories are managed by OS X. /usr/local/ would be OK, though. No matter where duplicity gets installed, there will still be a dependency on a python interpreter version. If you are using python.org installers, the standard place for site-packages is within the framework. If you need to upgrade that python version, you can easily re-install duplicity and its dependencies or you can move them out of the way when you perform a python upgrade. If you use the 10.5 Apple-supplied python, the site packages are installed in /Library/Python/Frameworks/ and shouldn't be disturbed by an Apple 10.5.x upgrade. You could also install a Macports python to use as your "production" python; macports also includes a duplicity port, though no idea how well it is maintained. Or, in theory, you could use virtualenv with any of those python versions to create a "frozen" virtual python environment and install duplicity there. -- Ned Deily, n...@acm.org _______________________________________________ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
