I have a redhat server that isnt resolving dependencies correctly.

I want to install httpd via yum "yum install httpd" and it installs correctly, but when i go to start httpd I get the following error:

/sbin/service httpd restart

Stopping httpd:                                            [FAILED]
Starting httpd: /usr/sbin/httpd: error while loading shared libraries: libaprutil-1.so.0: cannot open shared object file: No such file or directory
                                                           [FAILED]

It is missing the dependency for apr-util package.

Weirdly the i386 package is installed and not the x86_64 package. Can anyone shed any light on why the dependencies might not be resolved correctly?
