Sorry - no help. The code now looks like this (without olegen):

  #!/usr/bin/env ruby
  require 'rubygems'
  require 'win32ole'
  opc_automation = WIN32OLE.new 'Opc.Automation'
  p opc_automation.GetOPCServers # ok
  opc_automation.connect 'Matrikon.OPC.Simulation', 'test.rb'
  groups = opc_automation.OPCGroups
  group = groups.add 'test_rb_group'
  items = WIN32OLE_VARIANT.new(nil, WIN32OLE::VARIANT::VT_NULL)
  errors = WIN32OLE_VARIANT.new(nil, WIN32OLE::VARIANT::VT_NULL)
  group.OPCItems.AddItems 1, ['', 'Random.Int1'], [0, 1], items, errors



  ["ArchestrA.FSGateway.1", "Matrikon.OPC.SiemensPLC.1", 
"ArchestrA.DASSIDirect.1", "Prosys.OPC.Simulation", 
"Matrikon.OPC.Simulation.1"]
  test.rb:28:in `method_missing': (in OLE method `AddItems': ) 
(WIN32OLERuntimeError)
      OLE error code:0 in <Unknown>
        <No Description>
      HRESULT error code:0x80020005
        Typekonflikt.
          from test.rb:28:in `<main>'
