I'm not asking for anything.  I'm guessing at an explanation for what 
CRAN is asking.  I'm not part of CRAN or R Core.

But it seems like 2 versions should be sufficient:  build on the 
institutional version, test on your personal machine (or on one of the 
test services like WinBuilder, R-forge, R-hub, etc.).
