I'd like to get a feel how much apps and libs are affected by this.
Actually if kdepasswd would be an independent application, and if it would 
link to libkonq, it would do something like this:

find_package(LibKonq)
...
target_link_libraries(kdepasswd ${LIBKONQ_LIBRARIES} ... )


FindLibKonq.cmake could probably check whether it is called inside kdebase 
with libkonq or not (only slightly hackish) and act accordingly.
But I have the feeling that this would be quite some work, if we need to do 
this for every small app.

Can you make a list of affected apps and libs in (as many as possible) KDE 
modules ?

Would it be ok or Gentoo to have only very few library packages per KDE 
module, e.g. only 1 kdebase-libs package ?
