What went wrong?  You might want to start by getting a bound on _when_
it went wrong.  When was the last time you successfully started httpd?
The problem happened sometime after that.  Look in your logs for any
suspicious events.  Check /var/log/yum.log.  Any new packages?  Did a
yum transaction fail (postinstall might be tinkering with SElinux)?
Try "yum-complete-transaction".  Any configuration changes since then?

Might want to try "restorecon -rv /etc/httpd" as well.
