This is because dependencies stored in package database are recursive.
Even with pkgng.

With old /var/db/pkg was not easy to recursively calculete dependencies
when need, and this recursive list was pre-calculeted and stored. I
don't know why this is not fixed in pkgng.

For example if you have ports:
A -> B -> C -> D
in package database stored, that A depends on B+C+D, but should only
be stored that A depends on B.

This recursive dependencies causes different problems - many extra ports
to rebuild is only one of this problems.

glib among others depends on perl, so with recursive dependencies all
ports, that depends on glib will be rebuild by portmaster -r perl with
no profit from this rebuild.
