Sorry, this problem has been solved compiling the glibc21 with the
USAGI patch, but I
just have upgrade to Suse 7.1 which has the glibc22, and I have the 
same problem (for this I asked for where is the glibc22 patch in a
previous mail).

In a mail of Stig Venas, he said:

So, with glic 2.2, I can set an IPv6 address in /etc/resolv.conf
nameserver tag, can not I?

My /etc/resolv.conf (for Linux with glibc22 *without* any USAGI patches
is):

jrh@ladilla:~$ cat /etc/resolv.conf
#
# /etc/resolv.conf
#
# Automatically generated by SuSEconfig on Thu Mar 15 12:36:48
/etc/localtime 2001.
#
# PLEASE DO NOT EDIT THIS FILE!
#
# Change variables (NAMESERVER + SEARCHLIST) in /etc/rc.config instead.
#
#
search it.uc3m.es
#nameserver 3ffe:3328:6:ffff:2c0:26ff:fea0:adee
nameserver 163.117.139.31          

If I change the nameserver with an IPv6 address, all happens to work
correctly,
but the "ping6 mira.ipv6":

jrh@ladilla:~$ ping6 mira.ipv6
ping: mira.ipv6: Name or service not known  

The same happens with "nameserver <IPv4>". 
The name mira.ipv6 is a AAAA record.

If I make a ping to a A record, all works fine.
