Please explain why.

If libA.so changes its ABI, you have to rebuild the dependent ports. We
propose "portupgrade -rf libA-a.b.c" for this. With the current scheme
of implicit dependencies recording this works, but takes a lot more
time. Why the hell do I have to rebuild claws-mail when python changes?
There's no reason (I maintain claws-mail, and python is not part of the
explicit dependencies).

With listing the explicit dependencies, we just need to grep for ports
which use the libA port and bump the portrevision for them (there are
scripts which do this). Users now just have to run "portupgrade -r
libA-a.b.c" (without "-f") and as such rebuild less ports (specially
when GNOME or KDE are involved).

Sorry, but the implicit dependencies we have currently are massive
bloat. What is listed here is the _real_ installed situation. Feel free
to have a look at the script which extracts this information with
objdump (Tools/scripts/neededlibs.sh) and point out deficiencies.

Would you please provide technical details why you are opposed to lift
the Ports Collection to a higher feature/quality level?

Bye,
Alexander.
