In hindsight it indeed seems unlikely that the registry would contain this kind

Exactly, though nuking evokes something a bit less precise than what this 
actually does :)

I think that's a hack: save and nuke the port in question (manually), then
let rev-upgrade catch the broken dependents for you.

No, there's no such thing in the registry. The registry only has
per-port information, so the best you can do is a combination of 'port
provides' and 'port dependents'.

I don't understand how bzip2 and port rev-upgrade relate.

Hi,

A variant of my earlier question: is there a magic formula to query the 
registry which files (and/or ports) depend on a given binary file? IOW, an 
elegant alternative to something like

%> sudo bzip2 -v foo
%> sudo port -v rev-upgrade
%> sudo bunzip2 foo.bz2

Thanks,
R.
