Execution of yum and rpm command gives Macro error.

Issue

• Execution of "rpm" or "yum" command always display an error message "error: Macro % has illegal name (%define)".

  Eg:
  
  [root@example ~]# yum clean all
  error: Macro % has illegal name (%define)
  
  [root@example ~]# rpm
  error: Macro % has illegal name (%define)
  RPM version 4.3.3
  ....
  
  [root@example ~]# rpm -q rpmdb-redhat
  error: Macro % has illegal name (%define)
  rpmdb-redhat-4-0.20060803
  
  [root@example ~]# rpm -qf /usr/share/bash-completion/completions/yum
   error: /etc/rpm/macros.perl: line 34: Macro %global is a built-in (%define)
   error: /etc/rpm/macros.perl: line 35: Macro %global is a built-in (%define)
   error: file /usr/share/bash-completion/completions/yum: No such file or directory
