that explains everything.  
Why do you do so?

Instead: 

1) Start with no '.Rout.save'

2) R CMD check  <pkg>
   will produce one in  <pkg>.Rcheck/tests/myTest.Rout
   Copy it to the package source, i.e. typically

   cp <pkg>.Rcheck/tests/myTest.Rout <pkg>/tests/myTest.Rout.save

3) R CMD check  <pkg>  
   now *will* do the comparison and give no difference hopefully
