This shouldn't be too difficult to script - you can get the information
from ports(7), print-run-depends (and, if you are building from source,
print-build-depends). Or from pkg_info(8), -S.
However, this does not solve the problem of what programs can be safely
removed. For instance, amavisd-new now depends on gnupg; deleting gnupg
might not be my intention when removing amavisd-new, while removing all
the Perl dependencies - say, p5-Archive-Tar - does sound like something
you'd want to do.
All in all, one would have to be able to mark packages as either
'installed' or 'installed as a prerequisite'. I have a vague
recollection that I'd heard Marc Espie say something to the effect that
this was a desired feature that might be implemented at some point, but
this is not currently possible.
BTW, ISTR that Debian has some heuristics based on the existence of any
non-library, non-documentation files in a package (i.e., if this is the
case, some script prints and optionally removes them). Does anybody know
how well that works?
