How to report bug in build-deps?

[Colin Law]

When one does
sudo apt-get build-dep <some_app>
it should install all the packages to allow that app to be built.  How
do I report a bug in the build dependencies list for an app (there are
some deps missing).

Do I just report it against the app itself?

Google has failed me, or perhaps more accurately I have failed to
persuade google to help.
