That´s the situation (again):
eix sys-libs/glibc
[D] sys-libs/glibc
     Available versions:  (2.2)  [P]2.2.5-r10 [P]2.3.2-r12 2.3.5-r3 2.3.6-r4 
2.3.6-r5 2.4-r4 2.5-r2 2.5-r3 2.5-r4 **2.5.1 ~2.6 2.6.1 ~2.7 ~2.7-r1 ~2.7-r2
        {build debug erandom gd glibc-compat20 glibc-omitfp hardened 
linuxthreads-tls multilib nls nptl nptlonly pic profile selinux userlocales 
vanilla}
     Installed versions:  2.3.4.20040808-r1(i686-pc-linux-gnu-2.2)(08:48:34 
08.11.2007)(nls 
userlocales -build -debug -erandom -hardened -multilib -nptl -pic)
                          2.6.1(2.2)(09:55:15 12.06.2008)
(nls -debug -gd -glibc-omitfp -hardened -multilib -profile -selinux -vanilla)


Let´s see if i´ve got what you mean:
Because my system didn`t work anymore after removing glibc-2.3.4, with the 
help of ldd i should find some dependencies.
ldd `which bash`
        linux-gate.so.1 =>  (0xb7fda000)
        libncurses.so.5 => /lib/libncurses.so.5 (0xb7f77000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7f73000)
        libc.so.6 => /lib/libc.so.6 (0xb7e43000)
        /lib/ld-linux.so.2 (0xb7fdb000)

l /lib/libc.so.6
lrwxrwxrwx 1 root root 13 12. Jun 09:55 /lib/libc.so.6 -> libc-2.6.1.so

Within the few commands i´ve checked i was unable to find any dependency to 
glibc-2.3.4 :-(


thanks
