${misc:Depends} breaking with Module::Build

[Jens Porup <jens@porup.com>]

G'day,

Well, I finally got my in-house perl apps packaged correctly, but apt isn't
picking up the requires => packages listed in my Build.PL.

	dpkg-gencontrol: warning: unknown substitution variable ${misc:Depends}

My control file lists: 

	Depends: ${perl:Depends}, ${misc:Depends},

But the substitution is not happening.

How do I make Module::Build make these dependencies forcing and binding?
