Comment (by ricci@…):

 I disagree.  For example, wireshark depends on glib2.  In turn, glib2
 depends on libxml2, which, in turn, depends on zlib.  What I'm hearing is
 that we should include zlib as a direct dependency of wireshark because
 something wireshark depends on depends on something which depends on zlib.
 I think that's completely wrong, wireshark should not care what it's
 direct dependencies need.
 So far as users breaking a port by removing the dependencies of
 dependencies, they'd have to force the removal which is known to be a way
 to break things, whether the dependencies are direct or indirect.

 I do agree that it is a problem if a port is linking in something which is
 not somewhere in the dependency chain, and that those should be fixed.

 From a quick glance and the port-depcheck.sh and the dependency diff, it
 doesn't look like it takes into account the entire dependency chain.
