CentOS - Nov 2008 - SVN missing libexpat.so.0 while it is present

Hello,

Hopefully I am sending this to the correct mailing list but it seemed 
best suited for troubleshooting :-)

I am trying to fix Subversion which isn't working for me on one of our 
machines: every attempt to run 'svn ls' or 'svn co' ends in:
svnserve: error while loading shared libraries: libexpat.so.0: cannot 
open shared object file: No such file or directory

Which is strange as the symlink is present in /lib/libexpat.so.0 (which 
points to /lib/libexpat.so.0.5.0) and /usr/lib/libexpat.so.0 - I even 
tried copying an identical libexpat.so.0.5.0 from another machine. Next 
I ran 'ldd -r /usr/bin/svnserve':

As you can see, all libs are found and present. I tried installing a 
custom Subversion 1.5.1 RPM which also fails the same way. Finally I 
installed all build tools and build the SRPM into a binary RPM and guess 
what? It also fails...

I tried rebooting the server, running 'yum update' a couple of times and
right now I'm out of ideas....

I am running CentOS 5.2 - 32-bit in a virtual machine (don't think the 
latter matters but right now I don't know where to look for the cause).

Do you have any of those installed?

Try running "ldconfig"?
