Ok let me take a crack at this.
The dependant packages ARE installed as needed. But this is ho it works. 

USE flags are there to enable various bonus features of packages that you may 
like. IF you want to enable certain features then you change the USE flags 
in /etc/make.conf right? However its not as simple as just remerging the 
package, because other dependencies may be affected by the change in USE 
flags too. To catch all this emerge has an option --newuse, which tells the 
system to update all packages that have their use flags changed. 

So change your USE flags to include any features you want on your system, then
run
	emerge --ask --newuse --verbose world
or	emerge -avN world

This should show you a list of packages with the use flags listed next to each 
package and any flags that have changed will be highlighted with a '*', and 
you can type y or n in answer to the question about making it happen. 

If you change a lot of flags you may have a very long list of packages to 
update, but its worth it long term, because you get a functional feature set, 
that works for you :). As stated previously on this list, USE flags are 
described in the portage tree in /$PORTAGEDIR/profiles/use.desc

Most of this info is from 'man emerge' BTW.
