Having done that, the next (and final) squeak45 update to System-dtl.666 fails
due to an undefined EnvironmentRequest referenced in MCClassDefinition>>createClass.

I believe that adding Monticello-cwp.589 to the squeak45 repository will
fix the problem:

  Name: Monticello-cwp.589
  Author: cwp
  Time: 22 March 2014, 7:59:40.107 pm
  UUID: 46fa1e2f-2bf7-4950-82b1-1db31d5753f8
  Ancestors: Monticello-cmm.588
  Rename EnvironmentRequest to CurrentEnvironment.

I am not sure if this will require an update to the config maps, but I will
first copy Monticello-cwp.589 from trunk to squeak45 and see if that is
