I see you posted this question on the gcc mailing list:
http://gcc.gnu.org/ml/gcc-help/2003-08/msg00288.html
so I'll cc that list with my answer.

Did you see the similar messages:
http://root.cern.ch/root/roottalk/roottalk03/1246.html

My guess is that you compiled this program on a different
operating system, and you're trying to run the binaries
on RHAS 2.1.  If that's the case, then don't do that :-)
If you want binaries to be portable across versions
of Linux, then build it under the LSB; that's the only
way to make sure it'll work.  (As a first step, you
might try linking in the C++ libraries statically
when you build your app; maybe you can do this by
using gcc instead of g++, and specifying libstdc++.a explicitly,
but I haven't tried.  See also
http://www.google.com/groups?threadm=dd7a565c.0306190732.5ecb0bd4%40posting.google.com)

If the above doesn't help, i'd say you should report the problem to Red Hat and/or
ask on a red hat advanced server specific mailing list.  RHAS is supposed
to come with pretty good support...

The fix in my situation was to specify --enable-symvers=gnu
when building gcc (see http://sources.redhat.com/ml/crossgcc/2003-06/msg00165.html)
but since you're not building your own gcc, you really shouldn't be
running into the same problem I did, and my fix won't help.
