Hi,
Know it's not always possible to see deps using --tree, my other option was to use
"dep" script (for which i searched a replacement in my prev mail).
Running "dep -r category/package" displays packages for which this package is a dependency.
Bad that it's development has stoped, doesn't work with portage-2.1_preX.
To show how "--tree" works, see below (run on my system some minutes ago):
...
#emerge -DNu world -ptv

These are the packages that I would merge, in reverse order:

Calculating world dependencies ...done!

See the package above "speex" with label [nomerge] - this means speex *is* a dependency of xine.
Dependencies are also shown by indents, see the exempt.
Here you can't see the dependencies for "media-sound/audacity" (as in your case).
Will look in www.gentooexperimental.org for another script (remeber there were some).
PS: currently filing a Bug on speex as it doesn't compile ;-)
