>Description:
Using binary packages from http://ftp.fr.NetBSD.org/pub/pkgsrc/packages/NetBSD/amd64/7.0/All

$ pkgin install xfce4
[...]
---Mar 02 12:23:39: installing xfce4-4.12.0nb2...
pkg_add: no pkg found for 'tdb>=1.2.10', sorry.
pkg_add: Can't install dependency tdb>=1.2.10
[...]

But doing

$ pkgin install tdb
[...]
---Mar 02 12:25:39: installing tdb-1.3.8...
[...]

and then

$ pkgin install xfce4

produces no errors, but a working xfce desktop.
>How-To-Repeat:
On a fresh install of NetBSD 7.0

$ pkgin install tdb
>Fix:
Before installing xfce4, install tbd explicitly.
