You might consider using the union of the debian/control.in and
debian/control dependencies.
Using just debian/control.in will cause any build dependency automatically
added by CDBS to be ignored (i.e. precisely debathena-config-build-common
and a bunch of packages we don't build and thus can ignore).
The other thing that will go wrong is debathena-build-depends; for that I
wrote some code in our makefile generator to have it depend on every other
package for purposes of the build order.
