Wrong ELF class; libxml2

I'm running CentOS 5.4 64bit, and I'm attempting to migrate an Apache web site from Apache 2.0 to Apache 2.2. The Apache 2.0 instance is running on an old Fedora 32bit machine.

On the new box (as well as the old) I've compiled and installed from the source.

Attempting to run off the 2.0 httpd.conf, I get the following error:

httpd: Syntax error on line 237 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/lib/libxml2.so into server: /usr/lib/libxml2.so: wrong ELF class: ELFCLASS32

I have both 32b and 64b libxml2 packages installed:

Installed Packages
libxml2.i386 2.6.26-2.1.2
libxml2.x86_64 2.6.26-2.1.2
libxml2-devel.i386 2.6.26-2.1.2
libxml2-devel.x86_64 2.6.26-2.1.2
libxml2-python.x86_64 2.6.26-2.1.2

Any hints?

See line 237 in your config. If you're using LoadFile in your 64-bit
webserver, point to the 64-bit libxml library.
