This poses a question of goal. Your perspective is "if you want to build
Gnome, here's how to do it without dependency problems." Another possible
perspective is somewhat different. Say I need a functionality which some
program brings (eg. Dia) and I know what I already have installed. Then I
would need to know which libraries that I don't have installed Dia
requires. In this scenario your batch concept is not very useful.

But I hope that from gathering this data we would be able to draw various
diagrams (in Dia? :-) that should be able to provide interesting
information for all scenarios.

Well, since gnome-libs require ORBit, then ORBit is also implied
dependency. But I assure you that gnome-print doesn't do anything with
ORBit directly (no API calls). I would get linker errors otherwise.

OTOH, in my scenario (Dia example) implied dependencies are useful,
because it's annoying to go backwards through dependency list in order to
find out the first source tarball which needs to be compiled. But full
dependency list should be shown in another diagram; not in the "build full
Gnome" one.

Version information would also be very useful, but I'm afraid it's hard to
gather it. Another piece of information I forgot to write in the previous
mail: bonobo 1.0.4 wants ORBit 0.5.8 and it's not happy with 0.5.7.
