I would suggest that you will *compile* those packages
yourself (modutils, util-linux), even though at first
you should upgrade to the lattest version of glibc 2.0.7.

The lack of '__bzero' is a sign of oddish libraries at
package builder's system. Either due to some odd intrinsic
in the used gcc, or some other surprise.

Installing util-linux-2.9.8, and then trying

ldd /bin/login

will soon tell, which libc version is called for, and
possibly also tell, if there is the problem...

On the other hand, I am running 2.2.0 system with util-linux-2.8.
(Although with glibc 2.1 ..)
