Makes sense to me - doing the equery on the package that installed the  
binary (which may have a name unrelated).

IIUC, there are two tools useful for second/third opinions for this task;  
dep and pquery. Here's an example of their use on fftw:

dep -L fftw

pquery --vdb --revdep sci-libs/fftw

And as you idicated, do a revdep-rebuild after the manual deletion.

[gentoo-user] revdep-rebuild question

[Hartmut Figge]

Greetings,

after the emerge -uDN world of today i proceeded with revdep-rebuild
which found nothing to to. But i noticed, that the emerge recommended to
execute revdep-rebuild --library='libosp.so.*'. Doing this two packages
were found and emerged.

Now, shouldn't these have been found already by the previous revdep-rebuild?

I believe --library rebuilds everything that uses that library, not
broken packages.

To test my theory you can run the command again and see if it finds
the same 2 packages again. :)

And after the next revdep-rebuild --library='libosp.so.*' the same two
packages are found and rebuild. And so on.

Hard to understand a sentence with such many errors. A challenge. :)

A quick look at the ebuild for opensp shows that it will always print
that message - doesnt test if its really needed, and the revdep-rebuild
reccomendation will always rebuild "all" matching libs it finds - not
just ones that really need building.
