I think I've seen it.  The last time I around I followed a
script in a HOWTO using revdep-rebuild, and I ran into a lot of
problems during the re-compile: there were about a half dozen
packages that wouldn't rebuild.  Getting things going again
required about two days of masking different versions of
different packages (each of which required masking a bunch of
dependencies to get compatible versions of everything).
