Yes, I know, it's correct what you say, but this doesn't prevent to 
improve things. I'm not saying that tomorrow we'll have a perfect ports 
tree where all and only direct dependencies will be listed, but if we 
don't even start...
Currently we have exactly the opposite case: ports that have direct 
(maybe not needed) dependencies to libraries that are not recorded in 
Makefiles. This is the root cause of "portmaster -r" or aggressive bumps.
