Running setup scripts in %post

["Raymond, Jeff" <jar7@xxxxxxxxxxxxxxxxxxxxx>]

Hello,

    I am trying to install OpenOffice during the post setup.  There is a a simple script to do it.  It is just a shell script but the .install script is not running during the post phase.  I tried using the --interpreter swith with /usr/bin/bash as the shell but that does not work either does any one know how to make a shell script run in Post?

Thanks
Jeff
