emerge --info get_flash_videos

I tried to d/l a video from vimeo with get_flash_videos. It complains that XML::Simple is missing.

***
$> get_flash_videos http://vimeo.com/26818646          
Downloading http://vimeo.com/26818646
Using method 'vimeo' for http://vimeo.com/26818646
Must have XML::Simple to download 1 videos
***

The ebuild file states that the XML lib is an "optional dependency" - see below.
What does "optional dependency" mean? Did I forget to set a certain USE flag somewhere?

I tried
#> revdep-rebuild -vip 
#> emerge -p get_flash_videos
but none of the commands take any action here.

After manually emerging I get a different error message but -IMO - thats no matter here.

"optional dependency" means "runtime dependency" means "you need to install it yourself".

portage does not yet have runtime use deps to handle this case, and adding use flags means unnecessary rebuilding.
