Portage currently does not store any information about where a package was 
installed from. Therefore the best you can do is manually inspect the output 
of `eix --installed-overlay`. It will show all packages where the version you 
have installed exists in any overlay (and you can see if they exist in the 
tree too). That, however, only implies that they might have been installed 
from that overlay..

It does require app-portage/eix-0.8.x. Also if you use update-eix-remote you 
better (re)move the eix database (/var/cache/eix) and regenerate the database 
with `update-eix` first or you will get a lot of false positives. IOW you 
need the eix database to only contain installed overlays.
