linux-l: probleme mit ld/libc

[JSC]

hi,

ich quaele mich hier nun schon ein weilchen mit einem
library-problem rum.

nach installation der libc.so.6 (libc-2.0.5.so) funktionieren
einige tools nicht mehr. bei manchen paketen hilft einfach neu
uebersetzen, bei anderen nicht.

Hauptproblem: knews:
>ldd ./knews
     libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x40002000)
     libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x40012000)
     libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40055000)
     libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x4005d000)
     libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40071000)
     libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x4007c000)
     libc.so.6 => /lib/libc.so.6 (0x40113000)
     /lib/ld-linux.so.1 => /lib/ld-linux.so.2 (0x00000000)
>./knews
     ./knews: can't load library 'libXmu.so.6'

>ldconfig -v #zeigt die library in /usr/X11R6/lib an.
>export LD_LIBRARY_PATH=/usr/X11R6/lib;./knews
     Segmentation fault (core dumped)
>export LD_LIBRARY_PATH=/usr/X11R6/lib

     (gdb)

das interessante ist, dass knews nach libc/ld update und recompile
schonmal lief :-(

kennt jemand das verhalten ? 

wie muss /etc/ld.so.preload aussehen ?

bye
