How ? 
Does it use ldd ? Well, thats not reliable enought for me.

Perhaps you misunderstand me. 
I'm talking about some theoretical considerations what a package manager
can do and what it cannot do with current project modeling. (assuming 
there's no manual package maintaining like writing specfiles, etc)

Because its better for its machine ?
I'm talking about quite heterogenous environtments. 

Okay, you can build packages for several CPUs and platforms, but soon
it becomes too much to handle.

This a command to install/update a package (i.e. mplayer) 100% automatic,
but also honouring all site dependent stuff (i.e. platform, architecture,
pathes, languages, ...)
