Do you mean that even if the environment variable LD_LIBRARY_PATH is 
defined, it gets overridden by hardcoded rpath?

Or only that default lookup paths like /lib and /usr/lib gets overridden 
by rpath value (when LD_LIBRARY_PATH is *not* defined)?

If it is the first, then please update the Debian wiki page, and also 
drop a note about it to jurij at debian.org (I see that he is not 
subscribed to updates to that wiki page).

As I understand it, rpath has its sane uses, it is not a complete evil. 
Only for packaging as part of Debian (and derivatives) is it a 
definitive no-no.

Also, if I understand it correctly, the issue here is only with Ubuntu 
libraries being compiled with rpath - local jhbuild-compiled binaries 
should not cause trouble if having rpath (unless, of course, the rpath 
is wrong, but that is another issue altogether).
