I think this paragraph covers my concerns.

that's then Daniel's decision, and I've no strong opinion on this;
also I agree that our would probably look more readable if
we would have the pkg-config checks as macro, sub function, whatever ...
though I'd suggest that you wait for Daniel's and others comments before
you start to code more on this, and get finally frustrated if your work
doesnt make it into sources ...
