Hi Richard,

The reason I thought to create a libpci-dev package was because if
there is only pciutils-dev, it means the other things in pciutils are
then pulled into the SDK that you may not care about. Not that big a
deal with the SDK, but it seemed better to avoid it. I can see it being
fairly annoying to split out multiple *-dev packages for more complex
recipes though.

I'm not familiar with the packaging code, but I can try to take a look
at what it would take to tie the dev-pkgs dependency back to the the
single -dev package for the recipe.

Thanks,
Robert
