The program I pointed to earlier in the thread does this for BLFS.  The 
output ( looks like:

     k3b -> kdelibs [label="Required"];
     k3b -> cdrtools [label="Required"];
     k3b -> dvd_rw_tools [label="Required"];
     k3b -> cdrdao [label="Required"];

Writing something to parse it and write out something like:

k3b: kdelibs cdrtools dvd_rw_tools cdrdao
[tab]echo $@

Wouldn't be hard.

You'd have to add the few packages without dependencies in another way.
For extra credit, add indentation to the printout.
