You shouldn't do that, is my initial reaction. At least, it needs a very 
careful consideration.

The reason is that one of the major points is consistency, which is a central 
key to improved usability.

This will not hold for anything but your local hard drive, since you've 
patched kdelibs to depend on your local things.

Many thing could have gone wrong:

* You are in fact not linking to your new library, but some other library on 
your hd. Check by doing `ldd <yourlibrary>`
* You expect your changes to pop up somewhere in a program that hasn't been 
restarted. KDE for various reasons has changed the way programs are invoked, 
into forking from an existing process, basically. This can be disabled by 
using export KDE_IS_PRELINKED="dummy" in the shell your KDE session is 
running.
