Thanks! I hadn't noticed the existence of /var/cache/edb/dep. Using it
instead of /usr/portage/metadata/cache works flawlessly.

All interested, please check the attached new version. It includes all
suggestions which were made so far. It requires >=sed-4.0, otherwise
replace "xargs sed -s" by "xargs -l sed". If there aren't further
corrections/suggestions then I'll create a bug in bugzilla for it.

Unfortunately when doing this, emerge starts complaining that it can't
satisfy dependencies.
