You probably want this enabled. I think it's disabled by default because new 
users will have no idea whatsoever what to do about it. All it does is check 
the files it wants to install with what's on the disk. If there's a match, 
the existing files must only have been put there by the same package 
(ignoring version numbers).

If there's a collision, you get a huge big fat error message and a chance to 
find out why two different packages install the same file. Maybe you need to 
uninstall one, maybe it doesn't matter. If it's the latter, just

FEATURES="-collision-protect" emerge <package> 

and continue as normal. In any event, you get to decide what should happen. 
Every experienced gentoo user should be using this imho
