I don't see the current Xaw3d situation as a disaster [for XEmacs] with Daniel's patches. There is a serious problem for people who roll their own under Debian, it's also easy to detect under Debian. If you want, you can just puke "buggy Debian system, XEmacs.org washes its hands, write bugs(a)debian.org for more help"[1] and refuse to build. The problem with using a runpath under Linux is that there's no reason to believe that the build system and the run system have similar ld.so.confs. Since ld.so.conf is the normal way to handle these things on Linux, it will take real sophistication on the part of users, even developers, to figure out what goes wrong if we silently hardcode rpath and something does go wrong.

One guy in XFree86 I know tests his next-generation X libraries in exactly that way. I used to do that back when the Japanese patches to Debian X packages tended to really suck (especially, they didn't get pre- and postrm scripts right); getting the old behavior was just a matter of pointing LD_LIBRARY_PATH to where I'd copied my working libs. All this is theory; I don't really care any more myself and my XF86 buddy is a vi guy anyway. But who knows what bugs are going to appear next? I would like to see an option in ./configure, default it to hardcode the rpath is ok with me, announce the value in Installation.
