Hi Paul,

There is currently no dependency calculation for units. Only binaries
relies on dh_shlibdeps but the units do not have any mechanism.

What could be done is to check for {$LINKLIB} and {$LINK}, but I've
rather preferred for now to wait for bugs and add on request.

I'm not in favor of strict dependency because in most case one do not
need all the libs to link his program. However a recommends should be
fine, so that by default newbe users get fully working installation on
the cost of GiB/TiB!!

If you have a precise idea about how we can do that automatically,
please share it even at a very early stage, we can improve it together
before implementation.

Cheers,
