Do you mean that when you run "rpm -Uvh somepackage.rpm" or even "rpm -qa" you get the message "libexpat.so.0: cannot open shared object file: No such file or directory"? That is weird, because as far as I can tell (using "ldd") the binary for "rpm" is not linked to libexpat at all... It also does not seem to be in the dependencies of "rpm". Could you run the "rpm -q rpm" command and copy and paste the exact output of it here? A little more information about your problem would help, for instance, what version of CentOS (4 or 5) are you running, and what is the architecture (i386 or x86_64) of your machine? Could you please post the exact output of the command "uname -mri" here? One option to recover from this kind of issues is to boot the machine in rescue mode using a CentOS install CD or the LiveCD and reinstall the expat RPM from there. Do you have a CentOS install CD at hand that you could use to do that? HTH, Filipe
