make check fails on Arch Linux

[Justin]

I simply run make check, using duplicity-0.6.17. This is on a gentoo linux 64 bit system.

Could reproduce a similar behaviour in arch64 - duplicity 0.6.17-3

Alright, I know what part of this is. On Arch Linux, /usr/bin/python is a symlink to python3. On most other Linuxes I've seen, it's been a symlink to a version of python2.

This causes the mock duplicity script used in the tests to fail (written for python2, but is run under python3). I can workaround this by just porting the script to python3 (a good thing to do anyway). Then I hit another error, which I'm looking into.

[Justin (jlec)]

I don't think this is the issue. On my system the situation is that /usr/bin/python calls python in API version 2 not 3.

I'm going to tentatively mark this fix released. It's been a while and as far as I can tell, trunk and recent releases pass tests. Please reopen if you find differently. Thanks!
