When I made the EXPLICIT_PACKAGE_DEPENDS patch, I noticed that there  
is not only libtool at fault (reaction of the libtool developers was  
IIRC: it's not trivial to fix known problems for the cross-building  
case (for libtool-1.x?)), but also pkg-config and similar things  
(dependencies of dependencies where specified, e.g. your port links  
against liba, the pkg-config for liba also told to link against libb  
which liba depends upon but for which the ABI was not exposed to your  
port by liba, but this caused a record of libb to show up in binaries  
of your port). I do not know if the situation improved in _all_ ports,  
but some look more sane.

You can also have a look at  
/usr/ports/Tools/scripts/explicit_lib_depends.sh, thats a script which  
analyzes the recorded dependencies in binaries for a given port (this  
may be different from what is recorded in LIB_DEPENDS, and it can be  
different from it even if LIB_DEPENDS is 100% correct). So if a lib  
which is listed in the output changes the soversion, you _have_ to  
recompile this port, no matter if the binary has his hands in the ABI  
of the changed lib or not (that's the port->liba->libb case from the  
paragraph above).

Bye,
Alexander.
