Yes.

Explicit dependencies makes it more easy to just rebuild those ports
which use a specific lib which just had an ABI change. Our users want
this. And the script mentioned above makes this very easy. Install the
port you maintain, run the script and copy&paste. It's more reliable
than what we have now (making more or less educated guesses yourself).
If we have had this some years ago, we wouldn't had to write a gnome
update script. We just would have needed to run the above script over
an installed gnome to get the lib dependencies right.

I have some minor improvements for the script in progress, but as it is
now it is already very usable.

Here's the output of a run for epiphany so you can get an idea about
its dependencies (I collapse the += parts in my patches, collapsing
them in the script is on the TODO list, but correctness is more
important ATM):

I know what the reason for the "unknown" ones is and I already have an
idea how to fix the problem in some cases (I'm not sure we can fix it
in all cases). This problem appears just for a few ports (one problem
case is e.g. those ports which make use of LD_LIBRARY_PATH in scripts
instead of adding the path with ldconfig).

Ok, I skip the GNOME ports then.
