  Summary     : A powerful interactive shell
  Description :
  The zsh shell is a command interpreter usable as an interactive login
  shell and as a shell script command processor.  Zsh resembles the ksh
  shell (the Korn shell), but includes many enhancements.  Zsh supports
  command line editing, built-in spelling correction, programmable
  command completion, shell functions (with autoloading), a history
  mechanism, and more.

file blablabla from install of hal-0.5.8.1-62.el5.i386.rpm conflicts with file from package hal-0.5.8.1-62.el5.x64.rpm


  rpm -Uvh --force /var/cache/yum/rhel-x86_64-server-5/packages/hal-0.5.8.1-62.el5.i386.rpm

Now re-run yum update. Now everything works fine.
