Never mind this one. I've answered in a mail to Alex, but you can ignore

This is one of the ugliest-but-important hacks we have in our code.

First we had applications, and they were slow to load.
Then we turned the applications into libraries, that could be loaded from 
a special process called "kdeinit" and by a wrapper executable as well.
Later, we found out we were not allowed to dlopen(2) a library: we needed 
to have a module. So we created modules, libraries and applications.

$ which konqueror
$ ls /usr/local/kde3/lib/
$ ls /usr/local/kde3/lib/kde3/
$ ldd /usr/local/kde3/lib/kde3/  | grep konqueror 
=> /usr/local/kde3-r424191/lib/ (0xb7f21000)

Right, my mistake.

But, as I said in the other email: for compilation only. This shouldn't 
affect non-compilation jobs, like linking, yaccing, flexing, dcopidling, 
kconfig_compiling, etc.

"Add to rpath only what I tell you to" as opposed to "add to rpath 
everything under the sun plus whatever you find in .la files (which I 
didn't say I want)"

We don't name -lstdc++ in our command-lines, but if is found, 
it will be used, which means /usr gets added to rpath.

None, which is why they are "would be nice".
