i am sorry to tell you that this trick doesn't do the job right, 
either. The only reason why you get the dependencies right in the 
gnome-mag package is because of the order of the packages in 
debian/control (you have the library packages listed before the 
frontend packages). However, this behaviour isn't documented anywhere.

To build the library package before the frontend package independent 
of their order in debian/rules, you still have to chain the 
binary-predeb rules like this:

binary-predeb/gnome-mag:: binary-predeb/$(libgnome-magN)

My latest experiments show that this has to be done even before you 
include the first cdbs makefile. Again, I believe this should either 
be documented or done automatically.

Cheers,
Fabian
