not so sure ... if your old glibc is in /lib, then setting LD_LIBRARY_PATH to 
the new glibc is wrong -- the old loader will still be used (since /bin/ls set 
PT_INTERP to a hardcoded path).  you need to manually execute the new loader, 
tell the new loader where the new libs are, and then tell it the binary to 
execute.

but i've only been half following this discussion ... maybe i'm completely off 
base
