Log message for revision 124123:
  Have to clear cached envs to most faithfully reproduce existing behavior.
  
  For example, when doing a develop egg and subsequently using it,
  buildout will still have to "get" the dist and find it as an egg
  link.  If the env is magically updated when the egg is developed, then
  it no longer has to "get" the dist since it knows it has it.  This
  fixed the last of the test failures.
