Yes, on wheezy, dpkg >= 1.17.14 is not available. We should have added
the Pre-Depends to not be caught with that problem. I am adding it
now. However, it won't solve your problem (only upgrade problems from
wheezy to jessie). I don't have much idea about what to do in backports
without doing a lot of stuff manually.

It's a bit odd that installing dpkg-dev would solve anything. I just
think that this part of the script is ignored as the package already
believes it is at the right version. Installing anything else could have
solved the problem too.
