audio/gnome-media: should it be fixed to chase pulseaudio bump?

[Barbara]

After updating audio/pulseaudio to 0.9.17, the volume control on the panel was 
missing.

So, trying from a console:
$ gnome-volume-control
/libexec/ld-elf.so.
1: Shared object "libpulsecommon-0.9.15.so" not found, required by "gnome-
volume-control"

which was obviously solved by a portupgrade -f audio/gnome-
media.
