 What I mean is that if a transitive closure of dependencies is
 performed at packaging time, then there is no need to check for
 dependencies when installing the original package.

 Here is an example:

 A depends on B and D
 B depends on C
 C depends on D and E

 Currently the deps will be:

 A -> B,D
 B -> C
 C -> D,E

 When installing A, Pacman will:

 1) check deps for A, start installing B and D
 2) check deps for B and D, start installing C
 3) check deps for C, start installing E

 With a transitive closure scheme at packaging time, the
 deps would be:

 A -> B,C,D,E
 B -> C,D,E
 C -> D,E

 When installing A, Pacman could simply install B, C, D and E
 *without* checking their deps (-Sd) because these deps are
 necessarily already included in those for A.
