Yes, but none of those are libraries. The part I'm worried about is
``gradually migrate apps to 7 as and when we can''. That would mean
that apps that still use 6 and apps that are already switched to 7
cannot be installed at the same time. That's why I don't think this
is a good approach.

See above: If we want to have them side by side in pkgsrc, they
should not conflict.

Yes, me too. My preferred approach would be to get Blair's packages
in wip into shape so they can replace the version 6 packages. Blair,
what's left to do?
