Prerequisites:
========================================================

Required php extensions:

  - CURL

Required additional Drupal Modules:

  JQuery Update with manual update to jQuery 1.2.1 
  --------------------------------------------------------
  http://drupal.org/project/jquery_update

  release 5.x-1.0 updates to jQuery version 1.1.2

  IMPORTANT:

  cdm_dataportl requires jQuery version 1.2.1
  The contributed Drupal module 'jquery_update' however updates only to version 1.1.2, 
  thus a manual update as described in http://drupal.org/node/196140 is nessecary.  
  
  I addition you must edit compat-1.0.js: replace lines 24 - 26 by:
  
          /*
           * a.kohlbecker: unload is still a valid event type and must not be replaced! 
           *               compat-1.0.js breaks plugins wich are using this event e.g. thickbox
           *  => thus I removed load from var e.
           */ 
          var e = ("blur,focus, resize,scroll,unload,click,dblclick," +
            "mousedown,mouseup,mousemove,mouseover,mouseout,change,reset,select," + 
            "submit,keydown,keypress,keyup,error").split(",");
