Yes.

They don't appear to, at present:

$ port deps faac
Full Name: faac @1.28+universal
Build Dependencies:   autoconf, automake, libtool
Library Dependencies: mp4v2
$ port deps mpeg4ip
Full Name: mpeg4ip @1.5.0.1
mpeg4ip has no Build Dependencies, Runtime Dependencies, Fetch  
Dependencies, Library Dependencies, Extract Dependencies
$

They probably did at one point -- specifically at a point when you  
installed these ports, so those now-deleted dependencies are still  
recorded in your registry.

It should be fine to force the uninstallation in this case.

sudo port -f uninstall libmp4v2 @1.5.0.1_0

They seem to be tracking issues relating to the transition from  
libmp4v2 to mp4v2 but not specifically the issue of old dependencies  
remaining in your registry, which is a known deficiency of registry  
1.0 which is described here:

Yes, and as you see, I therefore downgraded pango from 1.26.0 back to  
1.24.5 in order to fix this problem:

Hopefully the pango developers will be able to figure out what caused  
this problem, and to fix it, and a future version of pango will again  
work well for us.

I'm sorry to hear that. I saw your other email about dbus bus errors  
but I'm afraid I have no insight on them. If you are having yet  
additional issues, please describe them.
