The problem is that emacs was built with '-rpath /usr/X11R6/lib'
causing it to use the libc6-based X libs instead of the libc5-based
ones.  This could have happened because emacs explicitly uses this
option or because it was built with an old xlib6-dev package which
automatically included it.  I've already filed a bug on emacs for this
yesterday.

The quickest way to work around the problem without removing xlib6g is
to edit the emacs binary, search for "/usr/X11R6/lib" and replace
"usr/X11R6/lib" with ASCII NUL characters.  If you don't know how or
can't do this, I've put a compressed, already-edited version at
ftp://ftp.ods.com/pub/linux/emacs.gz.  Just fetch it, uncompress it,
"chmod +x" it and copy it to /usr/bin.

I haven't noticed any other problems yet.  However, there is a
potential problem with Xaw3d and neXtaw just waiting to happen.  These
packages should be rebuilt ASAP with the proper libc dependency
explicitly compiled in.
