There is no azure USE flag in duplicity from the main tree, the
"(-azure)" notation you see means that flag is no longer here in
the new version to install.

No, it isn't. Your problem comes from a way how you installed
duplicity from rinaldus overlay. How this overlay is enabled? What
priority have you set?

What you basically need is to prefer overlay version over version
from the tree.

Eix shows me 6 overlays with this ebuild, but there is no
"rinaldus" on the list, it isn't in layman either. You should have
a record of your overlay somewhere in
  /etc/portage/repos.conf/*.conf
set
  priority = 50
for this overlay, so it will have precedence over the main
portage tree.

Another way to solve this issue is to mask duplicity only from
gentoo tree, add to your /etc/portage/package.mask:

  app-backup/duplicity::gentoo

This way it will be installed only from overlay(s), even if in-tree
version is newer.

Of course, the best solution is to file bug for
app-backup/duplicity and ask maintainers to add azure USE flag.
