That worked!  Very nice!  But, I had to apply the patches manually.
Email may have messed up the patch sets with new-lines and indentation.
Can this be added to the main stream?  I am on to learning 'env import'.
Thank you.

If email messed it up once, I guess it could mess it up again, but I
generated patches using:
