The profusion developers ran into the same issue, and started working on
it. Basically, I think the debian packages needed for test building should be
separated from those in the base "Fuego distribution". We can add
libpopt-dev to the toolchain installer script (I have nothing against that).
But in general this solution doesn't scale. If we have thousands of tests,
we can't be installing every library in existence. Each test should indicate
its own build dependencies (as you say), and we should only install the
ones needed for the tests that are installed in the system.

The problem with adding dbench to the target system is that this is
not a solution for testing final products. Final products should not have a bunch
of extra testing binaries on them. Most consumer products I've worked on
have two configurations: the developer configuration and the production
configuration. The production configuration usually has all the testing material
stripped out. This is especially important for low-footprint devices.

Which item are you working on? I was going to take a look at dbench and see
how dependent it is on libpopt. They just added this recently, so it might
not be that tightly integrated yet.
