In theory, all dependent packages should be tested anyway
before updating a package. But I concede that in practice this
very often is not done (and in this case it would have doubled
the effort, testing old and new binaries).
I don't know what the solution is. I tend towards the more
pragmatic approach: if I have enough reason to believe that a
package is backwards compatible and I have tested it with a
sufficient/representative number of dependencies, I usually
assume that it will work with other packages as well.

Okay, what about this: add a new INCOMPATIBLE_WITH (better
names welcome) entry that is stored in binary packages.
This entry lists the version number(s) of the same package
it is incompatible with. E.g., for tiff-3.6.1 we can set
Binary packages compiled against anything before tiff-3.6.1
will then not install against tiff-3.6.1, even though their
dependencies might, for example, be tiff>=3.5.5
This solves the problem for binary packages (assuming that
appropriate, newer versions are being uploaded onto ftp@),
while allowing people who compile their packages from source
to update whenever it suits them, rather then forcing them
into recompilation bonanzas.

IIRC, it was meant to stand for "NetBSD". It was invented
to allow for changed version numbers where there was a
(user-visible) change to the NetBSD package without the distfile

What about the above idea? I haven't read through the package
tools sources yet, but I believe this should be fairly
straightforward to implement.
Thoughts? Comments? Flames?
