CentOS 6 httpd killed by update

Panic Mode commences! I installed updates yesterday.

On restart, httpd yielded:

Starting httpd: /usr/sbin/httpd: symbol lookup error: `/usr/lib64/libaprutil-1.so.0: undefined symbol: apr_os_uuid_get

Running ldd -r generates the same message:

Short of downloading apache source, what are the options.

I already did a yum clean all and made sure I'm using only the base repositories. No updates available, yadda.

I'm downloading the apache2 source code while I await the obvious quick-fix answer.

You have an extraneous 32bit version of libapr installed. Visible in the following line.

libapr-1.so.0 => /usr/lib/libapr-1.so.0 (0x00007f121d587000)

You can find out what package owns that file by running rpm -qf /usr/lib/libapr-1.so.0.

That package might need upgrading (or removal if it is unused).
