newbie: up2date snafu

[Tim Wunder <wundertp rescobaltimore com>]

Hi, 
New to the list. 
Been using RedHat 7.0 for several months now as a samba server and
intranet web server, no real problems. 

Doing some maintenance with up2date and performed updates to the
following:
 gnorpm-0.95.1-6 
 mod-perl-1.24-6 
 nfs-utils-0.3.1-7 
 openssh 2.5.2p2-1 (openssh-askpass, openssh-askpass-gnome,
openssh-clients, openssh-server too) 
 perl-0.5.6-10a 
 procmail-3.21-0 
 rpm-4.02 (rpm-build, rpm-devel, rpm-python too) 
 sendmail-8.11.6 
 xinetd-2.3.3-1 
 openssl-0.95.9 
 python-xmlrpc-1.4-1 

Now, when I run up2date, it gives me this error: 

[root localserver RPMs]# up2date 
Traceback (innermost last): 
File "/usr/sbin/up2date", line16, in ? 
import up2date 
File "/usr/share/rhn/up2date/up2date.py", line 13, in ? 
import socket 
ImportError: symbol __sysconf, version GLIBC_2.2 not defined in file
libc.so.6 with link time reference 

If I remove the 2.5.4-1 version of up2date and re-install the 2.0.5
version, I still get the same error. How do I fix this? It seems to me
that something wants glibc 2.2 and I have 2.1.92 still installed. I'd
rather not try to update glibc at this point, but if that's the way to
go, I'll do it.

I've contemplated removing the rpm updates, but that's complicated by
the fact that you kinda need rpm around to use it for updating rpms. 

I posted a message on the RedHat Network support forum, then noticed
several other posts with the same problem. Nobody's responded with any
solution, yet.

Any help would be appreciated.

Regards,
