install requirements / instructions for ArcGIS License Manager for Linux

Idea created by ESandinesriaustralia-com-au-esridist Employee on Nov 23, 2011
    Could we please publish a document describing the prerequisites and installation instructions for the concurrent ArcGIS License Manager for Linux?  For example as of 10.0, x11 must be installed on the Linux host before the license manager can be installed.  However, this is not documented anywhere I can find.  A customer's only current way of determining the prerequisites is to run the installer and interpret the errors.  Thank you very much!
